The Nailor Model Series 6500 and 6200 Pattern Ceiling Diffusers have been specially designed to provide a high
capacity louvered face directional diffuser that can supply large volumes of air at relatively low sound levels and pressure
drops. An engineered blade design with a 1/4" (6) horizontal lip on all angular discharge louvers creates a stable horizontal
air pattern that is tight to the ceiling. Ideal for applications in VAV systems, these diffusers create a strong ceiling coanda
effect at typical maximum and minimum airflow rates and ensure draft free air distribution.
Available with a wide variety of core styles and neck sizes, a combination can be selected to suit a specified air pattern and
deliver the desired volume of air to suit any particular requirement. Many frame types are also available to suit almost any
mounting condition including surface mount (flat, beveled or deep drop face) and T-Bar panel types (Standard 1" (25),
Fineline, Spline, Tegular or Metal Snap-in). These models therefore offer a great degree of design flexibility.
The Nailor Model Series 6550 and 6250 Adjustable Pattern Ceiling Diffusers offer the same features as the 6500 and
6200 Series, however, they feature four hinged, individually adjustable deflecting vanes. These vanes allow air pattern
adjustment from horizontal to vertical and further enhance the flexibility of the diffuser. Ideal for applications with higher
ceiling heights or for heating applications to minimize stratification.
FEATURES:
Spring loaded core. Removable
without the use of tools.
High neck collars for solid connection.
Secure core attachment.
A wide variety of frame styles to suit
most ceiling applications.
Optional extended panels to suit
modular ceiling systems.
Engineered air diffusion patterns for
1, 2, 3 or 4-way blow in a wide
selection of square and rectangular
neck sizes (see page D16).
Clean lines with no unsightly visible
screws.
Square-to-round transition adaptors
are available (SR option).

Performance Notes:
1. Throw values are given for terminal
velocities of 150, 100 and 50 fpm
under isothermal conditions. Data
applies to ceiling mounted units when
the maximum coanda effect applies.
When no ceiling is present (exposed
duct), throws are reduced by
approximately 25%.
2. Sound levels in performance tables
are for steel construction Model
6500. Apply the following corrections
for aluminum construction Model
6200.
TP = Listed value x 1.25.
NC = Listed value + 4.

The Nailor Model Series 6500IV and 6200IV Pattern Ceiling Diffusers have been specially designed to provide a high
capacity, high induction, louvered face directional diffuser that can supply large volumes of air at relatively low sound levels
and pressure drops. An engineered blade design with a 1/4" (6) horizontal lip on all angular discharge louvers creates a
stable horizontal air pattern that is tight to the ceiling.
Induction vanes mounted behind the louvers create counter-flowing jets of primary air that promote rapid mixing of the cool
primary air with the warm room air. This high induction characteristic is ideal for VAV applications involving high cooling
loads as it quickly equalizes the air temperature, reduces the throw and minimizes the potential for uncomfortable drafts.
Available in a wide variety of core styles and neck sizes, a combination can be selected to suit a specified air pattern and
deliver the desired volume of air to suit any particular requirement. Many frame types are also available to suit almost any
mounting condition including surface mount (flat, beveled or deep drop face) and T-Bar panel types (Standard 1" (25),
Fineline, Spline, Tegular or Metal Pan Snap-in). These models therefore offer a great degree of design flexibility.
FEATURES:
Spring loaded core. Removable
without the use of tools.
High neck collars for solid connection.
Secure core attachment.
A wide variety of frame styles to suit
most ceiling applications.
Optional extended panels to suit
modular ceiling systems.
Engineered air diffusion patterns for
1, 2, 3 or 4-way blow in a wide
selection of square and rectangular
neck sizes (see page D37).

Model:
6400 Fixed Pattern
CEILING DIFFUSERS
The Nailor Model Series 6400 Fixed Pattern Ceiling Diffusers have been specially designed to provide an extra high
capacity louvered face directional diffuser that can supply large volumes of air at relatively low sound levels and pressure
drops. The Model 6400 differs from the 6200 Series diffuser only in that the leading edge on all angular discharge louvers
is straight, without the horizontal lip. This results in a relatively deeper primary air stream emanating from the diffuser, which
produces shorter throws and slightly lower sound levels. The 6400 Series relies on the ceiling coanda effect in order to
maintain the catalogued throws for engineered air distribution and performance and is recommended for applications with
higher ceiling heights or for heating applications to minimize stratification.
Available with a wide variety of core styles and neck sizes, a combination can be selected to suit a specified air pattern and
deliver the desired volume of air to suit any particular requirement. Many frame types are also available to suit almost any
mounting condition including surface mount (flat, beveled or deep drop face) and T-Bar panel types (Standard 1" (25),
Fineline, Spline, Tegular or Metal Snap-in). These models therefore offer a great degree of design flexibility.
FEATURES:
Spring loaded core. Removable
without the use of tools.
High neck collars for solid connection.
Secure core attachment.
A wide variety of frame styles to suit
most ceiling applications.
Optional extended panels to suit
modular ceiling systems.
Engineered air diffusion patterns for
1, 2, 3 or 4-way blow in a wide
selection of square and rectangular
neck sizes (see page D45).

Performance Notes:
1. Throw values are given for terminal
velocities of 150, 100 and 50 fpm under
isothermal conditions. Data applies to ceiling
mounted units when the maximum coanda
effect applies. When no ceiling is present
(exposed duct), throws are reduced by
approximately 30% with a downward
projection of approximately 30 degrees.
2. Performance data as tabulated is for
supply air conditions. Correction factors for
return air application - see next page.
3. Correction factors for round inlets - see
next page.
4. Data derived from tests conducted in
accordance with ANSI/ASHRAE Standard
70 2006.

CEILING DIFFUSERS
The Nailor 6400IV Induction Vane Pattern Ceiling Diffuser has been specially designed for optimum performance in both
heating and cooling applications. The 6400IV is a high capacity, high induction, louvered face directional diffuser that can
supply large volumes of air at relatively low sound levels and pressure drops.
The diffuser features aerodynamically designed straight angled louvers on 1 1/2" (38) centers. The induction vanes,
mounted on the back of each louver are also spaced on 1 1/2" (38) centers and angled at 45 degrees. Vane sets on
adjacent parallel louvers run in opposite directions and cause primary air to emerge from each louver at alternating angles.
The induction vanes create counter-flowing jets of turbulent discharge air that promote high induction rates and rapid
temperature equalization. This high induction characteristic is ideal for VAV applications involving both high cooling and
heating loads, producing superior room air mixing while minimizing the potential for uncomfortable drafts in the occupied
space.
Available in a wide variety of core styles and neck sizes, a combination can be selected to suit a specified air pattern and
deliver the desired volume of air to suit any particular requirement. Many frame types are also available to suit almost any
mounting condition including surface mount (flat, beveled or deep drop face) and T-Bar panel types (Standard 1" (25),
Fineline , Spline, Tegular or Metal Pan Snap-in). These models therefore offer a great degree of design flexibility.
STANDARD FEATURES:
Spring loaded core. Removable
without the use of tools.
High neck collars for solid connection.
Secure core attachment.
A wide variety of frame styles to suit
most ceiling applications.
Optional extended panels to suit
modular ceiling systems.
Engineered air diffusion patterns for
1, 2, 3 or 4-way horizontal blow in a
wide selection of square and
rectangular neck sizes. (See page
D65).
Clean lines with no unsightly visible
screws.

SUGGESTED SPECIFICATION:
Furnish and install Nailor Model 6400IV High Capacity Induction Vane Pattern Ceiling Diffusers of the size and type shown
on the plans and air distribution schedules. Diffusers shall be designed for optimum performance in both heating and cooling
applications. Diffuser shall be of extruded aluminum construction with miscellaneous steel components. Blades and frame shall
have reinforced staked mitered corners for high quality appearance and function. Diffusers shall consist of an outer frame
assembly to suit the application shown, which includes an integral collar for connection to the square or rectangular duct size
indicated. A square to round transition collar shall be supplied where indicated to facilitate attachment of round duct.
An inner core assembly consisting of fixed deflection louvers on 1 1/2" (38) centers, capable of producing either a 1, 2, 3 or
4-way horizontal airflow discharge pattern as indicated on the plans shall be securely held in place by a spring loaded
mechanism without the need for visible screws. The deflection angle of each louver shall be constant (diffuser designs with a
horizontal lip at the point of discharge are not acceptable). Aluminum induction vanes on 1 1/2" (38) centers shall be mounted
in extrusion slots and welded to the rear of each louver of the inner core. The vanes shall be orientated at 45 in opposite
direction on alternating louvers to promote rapid temperature equalization and ensure high induction and rapid mixing of the
primary and room air. The core shall be fully removable in the field without tools for the purpose of installation, cleaning or
damper adjustment. Diffuser finish shall be AW Appliance White baked enamel (optional finishes are available).
(Optional) An opposed blade damper constructed of heavy gauge corrosion-resistant steel (aluminum is optional) shall be
provided with all units.
The manufacturer shall provide published performance data for the diffuser, which shall be tested in accordance with
ANSI /ASHRAE Standard 70-2006.

CEILING DIFFUSERS
VAV systems, the air may fall away from the ceiling or
dump, producing drafts in the occupied space during
cooling. Air emanates from this diffuser design at an angle
of approximately 20 degrees down from the ceiling. It is
therefore not recommended for ceiling heights below 10'
6" due to the possibility of excessive velocities in the
occupied space. Figure 3 illustrates the currently popular
pattern diffuser, which features the addition of a horizontal
lip on the leading edge of the louvers (e.g. Nailor Models
6200 and 6500). This feature was added by most
manufacturers to help maintain good ceiling effect at low
flows during cooling when VAV systems became
predominant. However this design increases the risk of
stratification and short circuiting during the heating mode.
The Nailor 6400IV Induction Vane Diffuser has been
designed to optimize performance in both heating and
cooling applications. Figure 4 illustrates a typical isovel
envelope for the Nailor 6400IV diffuser. The depth of the
envelope is somewhere between the aforementioned
diffuser designs. Induction vanes increase turbulence as
the conditioned air enters the space, resulting in an
increase in room air induction and more rapid temperature
equalization. Notice that the induction vanes also produce
an increase in the spread of the air stream. This produces
a more evenly distributed air pattern with shorter throws.
Diffuser placement flexibility is therefore increased and
the potential for opposing diffuser air streams colliding
and entering the occupied space is reduced.
The Nailor 6400IV diffuser is therefore the perfect choice
for commercial applications where comfort cooling and
heating is desired.

These illustrations are provided for guidance purposes in order to illustrate the relative difference between pattern ceiling diffusers with and
without induction vanes. The 150 fpm throw isovel for a 12" x 12" neck @ 400 cfm is illustrated. A 4-way diffuser is shown, but the airstream
projection is only shown in one direction for reasons of space and is the same for the other three sides.

Performance Notes:
1. All pressure are in inches w.g..
2. Throw values are given for terminal velocities of 150,
100 and 50 fpm under isothermal conditions. Data
applies to ceiling mounted units when the maximum
coanda effect applies. When no ceiling is present
(exposed duct), throws are reduced by approximately 25%.
3. NC (Noise Criteria) values are based on 10 dB room
absorption, re 10-12 watts.

CEILING DIFFUSERS
The Nailor RNS Series Square Ceiling Air Diffusers have been specially designed to provide an extremely cost effective,
value engineered product. They offer both the unobtrusive appearance required for architectural excellence and the 360
diffusion pattern at minimum NC levels required for high engineering performance. For these reasons the RNS Series
diffuser is the most popular choice for general applications.
The stamped one-piece cones eliminate mitered corners and the die-formed curves provide consistent quality and
performance. The stepped down core design increases capacity and minimizes streaking and smudging of the ceiling.
The diffusers provide stable diffusion and mixing patterns under constant and changing load conditions and are particularly
suitable for variable air volume systems.
The diffusers are available with various frame/border designs to suit many ceiling systems including surface mount, T-Bar
lay-in, and panel applications. Standard finish is a high quality baked enamel for long life and easy cleaning. A variety of
neck sizes are available to suit your system design. The collar is a full 1 1/4" (32) in height for easy, secure connection.
Steel models are available in all size and frame type combinations. Aluminum models are available in a 24" x 24"
(610 x 610) and a 20" x 20" (508 x 508) full face Type L frame module and 12" x 12" (305 x 305) modules with a full face
Type L or Type S frame.

Model RNSA
The Nailor Models RNSA and ARNSA Adjustable Square Ceiling Air Diffusers have been specially designed to provide both
the unobtrusive appearance required for architectural excellence and the 360 diffusion pattern at minimum NC levels required for
high engineering performance. They provide the flexibility of a standard horizontal discharge or near vertical discharge pattern,
useful in high ceiling applications where better air penetration or spot heating may be desired. The stamped one-piece cones
eliminate mitered corners and the die-formed curves provide consistent quality and performance.
The adjustable diffusers provide stable diffusion and mixing patterns under constant and changing load conditions and are
particularly suitable for variable air volume systems. They are available to suit many situations including surface mount,
T-Bar lay-in and panel applications. Standard finish is a high quality baked enamel for long life and easy cleaning. A variety of
neck sizes are available to suit your system design. The collar is a full 1 1/4" (32) in height for easy, secure connection.
FEATURES:
Removable core.

CEILING DIFFUSERS
The Nailor RNS3 Series Square Ceiling Air Diffusers have been specially designed to provide an extremely cost
effective, value engineered product. They offer both the unobtrusive appearance required for architectural excellence and
the 360 diffusion pattern at minimum NC levels required for high engineering performance. For these reasons the RNS3
Series diffuser is the most popular choice for general applications.
The stamped one-piece cones eliminate mitered corners and the die-formed curves provide consistent quality and
performance. The stepped down core design increases capacity and minimizes streaking and smudging of the ceiling.
The diffusers provide stable diffusion and mixing patterns under constant and changing load conditions and are particularly
suitable for variable air volume systems.
The diffusers are available with a frame/border design to suit a lay-in T-bar ceiling and can also be surface mounted using
the optional drywall diffuser frame. Standard finish is a high quality baked enamel for long life and easy cleaning. A variety
of neck sizes are available to suit your system design. The collar is a full 1 1/4" (32) in height for easy, secure connection.

CEILING DIFFUSERS
The Nailor Model RNS2 Square Ceiling Air Diffuser has been specially designed to provide the mechanical engineer with the
most cost effective engineered diffuser currently available in the industry. It combines the high performance expected from a
louvered face type ceiling diffuser with a cost as low as any lesser performing commercial diffuser currently available. The RNS2
has a 360 diffusion pattern at minimum NC levels required for high engineering performance. The diffuser provides stable
diffusion and mixing patterns under constant and changing load conditions and is eminently suitable for variable air volume
systems. It can accommodate a turn down of 80% without losing the ceiling coanda effect and dumping. The stamped one-piece
cones eliminate mitered corners and the die-formed curves provide consistent quality and performance.

CEILING DIFFUSERS
The Nailor Model Series TWR "Twister" Stamped Square Ceiling Diffuser is a high performance ceiling diffuser that is ideal
for VAV applications. The name "Twister" is given to this diffuser because of its tight horizontal 360 swirl air pattern. The
contemporary architectural radial vane design produces an unmatched high induction swirl pattern engineered to optimize
occupant comfort by minimizing stratification over a wide range of air volumes. The "Twisters" superior coanda effect air pattern
eliminates dumping and is ideal for VAV applications.

Balancing:
It is recommended that a
commercially available Flow
Hood is used for field balancing.
The airflow meter directly reads
average flow rate with great
accuracy at all volumes. It is a
much faster and more accurate
alternative to time consuming
multiple
velocity
readings,
eliminating the use of Ak factors
and the calculations required to
convert the average velocity into
airflow.

CEILING DIFFUSERS
The Nailor Model Series 'UNI' Square Ceiling Air Diffuser has been specially designed to provide both the unobtrusive
appearance required for architectural excellence and the 360 diffusion pattern at minimum NC levels required for high
engineering performance. The stamped one-piece outer cone eliminates mitered corners and the die-formed curves provide
consistent quality and performance.

CEILING DIFFUSERS
The Nailor Model 'UNI-PD' Fixed Perforated Downblast Square Ceiling Diffuser has been specially designed to provide both
the unobtrusive appearance for architectural excellence and the high airflow at minimum NC levels needed in theater, auditorium
and other high ceiling applications. A circular perforated aperture in the diffuser face provides both a horizontal and vertical
apportion of the airflow. The horizontal portion provides a tight 360 ceiling diffusion pattern and the vertical portion provides a true
and long downward projection.

CEILING DIFFUSERS
The Nailor Model 'UNI-AD' Adjustable Downblast Square Ceiling Diffuser has been specially designed to provide both the
unobtrusive appearance for architectural excellence and the high airflow at minimum NC levels needed in theater, auditorium and
other high ceiling applications. Radial vanes in the adjustable face damper permit air pattern adjustment from full horizontal to
approximately 50/50 horizontal/vertical. Full adjustment requires only a half turn and is easily accomplished from the floor using
the ring operator and a pole (by others).
The Model UNI-AD heavy duty ceiling diffusers are designed for effective heating and spot cooling applications where conditions
and floor to ceiling heights are variable. At the full vertical setting, they provide a true and long downward projection. At full
horizontal setting, they produce the tight ceiling pattern that is required for excellent VAV performance.
Designed to integrate with the popular lay-in type ceiling grid system, this diffuser offers simple installation and a highly economical
alternative to the more expensive round spun downblast diffuser design.
Engineered air diffusion pattern.
Steel stamped shapes for uniformity.
High neck collars for solid connection.
Fixed inner core.
Suitable for theaters, auditoriums,
factories, warehouses, convention halls,

CEILING DIFFUSERS
The Nailor 5000CTD Series Diffusers have been designed with the architect in mind to provide an unobtrusive high
performance ceiling diffuser that incorporates a center ceiling tile (by others) that matches the surrounding ceiling system. This
product is available in a nominal size of 24" x 24" (600 x 600) to suit both imperial and metric exposed grid suspended ceiling
systems. The 4-way blow linear slot design utilizes the 'ice-tong' premium quality pattern controller, providing a tight horizontal air
pattern, which can accommodate high turn down ratios and is therefore eminently suitable for variable air volume systems.

Model 6600
The face panel, which is located below the ceiling line, provides a horizontal discharge and a 360 diffusion pattern at minimum
NC levels required for high engineering performance. This makes the 6600 Series ideally suitable for VAV systems. The face
panel is adjustable by means of four spring-loaded countersunk screws located at the four corners of the panel which can be
positioned to provide a 1/2" (13) to 1 1/4" (32) variable opening. This provides great flexibility, as the diffusers length of throw at
any given air volume may be increased or decreased in order to adapt to field conditions.
The 6600 Series are designed for both surface mount and lay-in T-Bar applications with the addition of a ceiling module sized
panel. The collar is a full 1 1/2" (38) in height for easy, secure duct connection.
FEATURES:
Square duct sizes are available in 3"
(76) increments.
Minimum Size: 6" x 6" (152 x 152).
Maximum Size: 18" x 18" (457 x 457).

Performance Notes:
1. Throw values are given for a terminal
velocity of 50 fpm under isothermal
conditions.
2. Data derived from tests conducted
in accordance with ANSI/ASHRAE
Standard 70 2006.
3. The addition of direction blow blankoffs reduces the effective area and for a
given air volume, increases the
discharge velocity with a resultant
increase in throw, pressure drop and
sound level. To determine throw, select
the diffuser as if it were supplying a
larger volume of air. The table shows
the percentage increase required to
determine diffuser airflow selection to
determine throw.
Corrections to pressure drop and NC
level may be approximated by using
correction factors as shown and applying
them to the 4-way blow value listed in
the performance tables.

Performance Notes:
1. All pressures are in inches w.g.
2. Throws are given at 150, 100 and
50 fpm terminal velocities, under
isothermal conditions.
3. NC (Noise Criteria) values are
based on 10 dB room absorption, re
10-12 watts. Dash (-) in spaces
indicates an NC level of less than 15.
4. Data derived from tests conducted
in accordance with ANSI/ASHRAE
Standard 70 2006.

Balancing:
It is recommended that a commercially
available Flow Hood is used for field
balancing. The airflow meter directly
reads average flow rate with great
accuracy at all volumes. It is a much
faster and more accurate alternative
to time consuming multiple velocity
readings, eliminating the use of Ak
factors and the calculations required
to convert the average velocity into
airflow.

CEILING DIFFUSERS
The Nailor RNR Series Round Ceiling Diffusers feature three concentric cones in all sizes to offer a balanced appearance
where different sizes are used in the same area. The diffusers deliver the air in a true 360 radial horizontal pattern and produce
excellent performance in variable air volume systems.
The Models RNR and ARNR feature infinite horizontal discharge patterns that allow the diffusers to accommodate different flow
rate conditions. Position A (cones down) provides maximum capacity at minimum NC levels while Position B (cones up) provides
higher induction and more air movement.

CEILING DIFFUSERS
The Nailor RNRA1 Round Ceiling Diffuser features three concentric cones in all sizes to offer a balanced appearance where
different sizes are used in the same area. The diffusers deliver the air in a true 360 air diffusion pattern and produce excellent
performance in variable air volume systems.
The Model RNRA1 is designed for both heating and cooling applications. The air discharge pattern is fully adjustable between
horizontal and vertical. The discharge pattern is adjusted by sliding the core up or down. In the "down" setting, capacity is
maximized and throw is horizontal. In the "up" setting, air projects vertically down from the diffuser.

Performance Notes:
1. Radius of diffusion values are given at
100 and 50 fpm terminal velocities under
isothermal conditions.
2. Performance data as shown is for the
diffuser only, with the cones in the "down"
position. Performance for the cones in
the "up" position can be approximated by
multiplying the total pressures by 1.6,
adding 5 NC to the sound levels, and
multiplying the radius of diffusion by .90.
3. Data derived from tests conducted in
accordance
with
ANSI/ASHRAE
Standard 70 2006.

CEILING DIFFUSERS
Model R-UNI
The Nailor Model R-UNI Round Plaque Ceiling Air Diffuser has been designed to provide both the appearance required for
architectural excellence as well as high engineering performance. These diffusers are suitable for both architectural ceilings and
exposed duct applications.
The diffusers deliver the air in a true 360 air pattern and provide excellent performance in variable air volume systems. The
discharge setting is simply adjusted by sliding the inner face plaque assembly up or down. The diffuser provides higher induction
and more air movement in the higher position while maximum capacity at minimum NC levels can be obtained in the lower
position.
FEATURES:
Smooth heavy duty face plaque is
1/8" (0.125) thick aluminum for strength
and lightness.
A spring clip arrangement permits
quick, easy installation and removal of
the inner cone assembly.
The core is retained by a spring
loaded friction arrangement. There are
no screws to reposition.

Balancing:
It is recommended that a commercially
available Flow Hood is used for field
balancing. The airflow meter directly
reads average flow rate with great
accuracy at all volumes. It is a much
faster and more accurate alternative to
time consuming multiple velocity
readings, eliminating the use of Ak
factors and the calculations required to
convert the average velocity into
airflow.

The Nailor Model RDB Round Downblast Diffusers have been designed for industrial and commercial applications. The unique
contemporary design features a " Fibonacci spiral " adjustable aperture. The discharge pattern can be adjusted from full horizontal
to full vertical. At the full vertical setting, the diffuser forces approximately 75% of the air in a long downward projection. This results
in effective spot cooling or heating from high mounting locations.

Model 4320
The Nailor Perforated Ceiling Diffusers have been designed to provide both the unobtrusive, smooth appearance
preferred by many architects and the high engineering performance required for use in heating and cooling applications.
They project a tight, uniform horizontal blanket of air over a wide range of air volumes and provide excellent performance
in variable air volume systems.
The 4320 Series features four individual stamped pattern controllers mounted on the rear of the diffuser face. They are
easily field adjustable to suit the desired air pattern. Model 4325 features a dropped (extended) face panel that is available
to compliment tegular tile ceiling systems, so the panel remains flush with the ceiling line. In non-tegular ceilings the throw
is reduced slightly and the airflow projection protects the ceiling against smudging.
FEATURES:
Round or square necks available.
Hinged, removable face plate with
quick-release spring latches.
Discharge pattern can adjust to
vertical or 1, 2, 3 or 4-way horizontal,
before or after installation.
Discharge pattern is adjusted by
dropping the perforated face and
rotating the pattern deflectors.
Inlet collar has 1 1/4" (35) depth for
easy duct connection.

Balancing:
It is recommended that a commercially
available 'Flow Hood' is used for field
balancing. The airflow meter directly
reads average flow rate with great
accuracy at all volumes. It is a much
faster and more accurate alternative to
time consuming multiple velocity
readings, eliminating the use of Ak
factors and the calculations required
to convert the average velocity into
airflow.

CEILING DIFFUSERS
Model 4320CB
The Nailor 4320CB Curved Blade Diffusers provide the unobtrusive, smooth appearance preferred by many architects
with superior features and performance characteristics. Designed to maximize throw, this model features individually
adjustable, friction pivoted curved blade deflectors mounted directly under the neck. They project a tight, uniform horizontal
blanket of air over a wide range of air volumes and provide excellent performance in variable air volume systems.
The 4320CB Diffuser features a 4-way adjustable discharge pattern as standard. The deflector blades can be adjusted to
control both the angle of discharge and hence throw from full horizontal to vertical in each direction and also damper the
air volume. By closing off the deflectors in one or more directions, directional control can also be achieved. The 4320CB is
also available with a factory supplied 1, 2 or 3-way adjustable discharge pattern controller.
The 4325CB features a dropped (extended) face panel that is available to compliment tegular tile ceiling systems, so that
the panel remains flush with the ceiling line.
FEATURES:
Round or square necks available.
Hinged, removable face plate with
quick-release spring latches.
Discharge pattern can be adjusted
from horizontal to vertical before or
after installation.
Discharge pattern is adjusted by
dropping the perforated face and
moving the curved blade deflectors.

Balancing:
It is recommended that a commercially
available 'Flow Hood' is used for field
balancing. The airflow meter directly
reads average flow rate with great
accuracy at all volumes. It is a much
faster and more accurate alternative to
time consuming multiple velocity
readings, eliminating the use of Ak
factors and the calculations required to
convert the average velocity into
airflow.

Model 4340CB
CEILING DIFFUSERS
The Nailor 4340CB Curved Blade Diffusers are designed to compliment the Nailor 4320CB curved blade ceiling diffusers
and feature the same individually adjustable, friction pivoted curved blade pattern controllers. Designed to maximize throw,
they project a tight, uniform horizontal blanket of air over a wide range of air volumes and provide excellent performance
in VAV systems.
The 4340CB is a square neck grille frame style design, featuring full face pattern controllers, for surface mount installation
in hard ceilings. A 4-way adjustable discharge pattern is standard. The pattern controllers may also be used to damper the
air volume and by closing them off in one or more directions, directional control can also be achieved. Also available with
a factory supplied optional 1, 2 or 3-way adjustable discharge pattern controller.
FEATURES:
Available in nominal duct sizes from
6" x 6" (152 x 152) to 24" x 24" (610 x
610) in 2" (51) increments.
Curved blades on 1" (25) centers
are individually adjustable and
regulate angle of discharge.
Frame is mechanically interlocked
for strength with hairline mitered
corners. Standard diffuser has a
4-way (B4) discharge pattern.
Removable face has concealed
latches for easy access to core.

The Nailor 4320F Series Perforated Diffusers combine smooth, unobtrusive architectural appearance with the superior
performance characteristics required by engineers. Designed to maximize throw, these models feature a single heavy
gauge stamped pattern controller that is mounted directly under the neck. The formed louver air pattern controller has
curved vanes that optimize airflow projection and provide a superior horizontal air pattern with a strong ceiling coanda
effect. An excellent choice for variable air volume systems.
A main benefit of the 4320F Series design is that the factory set 4-way discharge pattern controllers can be field adjusted
to a 1, 2, or 3-way pattern. You can be assured that once installed, be it long or short term, the air pattern projection and
performance will remain constant.
The 4325F features a drop (extended) face panel that is available to compliment tegular tile ceiling systems. This ensures
the panel remains flush with the ceiling line.
FEATURES:
Round or square necks available.
Hinged, removable face plate with
quick-release spring latches.
Factory set 4-way discharge pattern
can be field adjusted to a 1, 2, or 3
way deflection.
Rugged curved vane air pattern
controllers ensure performance is
always optimized.

Balancing:
It is recommended that a commercially
available 'Flow Hood' is used for field
balancing. The airflow meter directly
reads average flow rate with great
accuracy at all volumes. It is a much
faster and more accurate alternative to
time consuming multiple velocity
readings, eliminating the use of Ak
factors and the calculations required to
convert the average velocity into
airflow.

CEILING DIFFUSERS
The Nailor 4320M Perforated Modular Core Diffusers provide the unobtrusive, smooth appearance preferred by many
architects and combines this with the flexible features of a high performance modular core design. This model features four
individual, spring-loaded modular pattern controllers mounted in the neck. They can be adjusted before or after installation,
to provide a 1, 2, 3 or 4-way discharge pattern by simply dropping the perforated face and rotating one or more of the
pattern controllers.
The engineered modular core design maintains a tight, uniform horizontal throw pattern from maximum to minimum cataloged
air volumes. It therefore provides excellent performance in variable air volume systems. The diffuser is shipped from the
factory with the modular core set for a 4-way discharge pattern.
The 4325M features a dropped (extended) face panel that is designed to compliment tegular tile ceiling systems. The face
panel is suspended flush with the ceiling line, providing both an aesthetically pleasing appearance and ensuring optimal
performance is maintained.
Model 4320M
FEATURES:
Square neck is standard.
Hinged, removable face plate with
quick-release spring latches.
Discharge pattern can be adjusted
to a 1, 2, 3 or 4-way horizontal pattern
before or after installation.
Discharge pattern is adjusted by
dropping the perforated face and
rotating the modular sections.

Balancing:
It is recommended that a commercially
available 'Flow Hood' is used for field
balancing. The airflow meter directly
reads average flow rate with great
accuracy at all volumes. It is a much
faster and more accurate alternative to
time consuming multiple velocity
readings, eliminating the use of Ak
factors and the calculations required
to convert the average velocity into
airflow.

CEILING DIFFUSERS
The Nailor 4320MR Perforated Modular Core Diffusers provide the unobtrusive, smooth appearance preferred by many
architects and combines this with the flexible features of a high performance modular core design. The low profile backpan
features an integral round neck which eliminates the need for adapters. Four individual spring-loaded adjustable modular
pattern controllers are mounted inside the backpan. This positions the leading edge of the pattern controllers near the
perforated face and flush with ceiling for optimum performance. The engineered design maintains a tight, uniform horizontal
throw pattern from maximum to minimum cataloged air volumes and therefore provides excellent performance in VAV
systems.
Discharge pattern can adjust to 1, 2, 3 or 4-way horizontal, before or after installation.
Discharge pattern is adjusted by dropping the perforated face and rotating the pattern deflectors. Diffusers are shipped from
the factory with a 4-way discharge pattern.
The 4325MR features a dropped (extended) face panel that is designed to compliment tegular tile ceiling systems. The face
panel is suspended flush with the ceiling line, providing both an aesthetically pleasing appearance and ensuring optimal
performance is maintained.

CEILING DIFFUSERS
Model 4340M
The Nailor 4340M Modular Core Diffusers are designed to compliment the Nailor 4320M and 4320MR modular ceiling
diffusers and feature the same flexible high performance modular core design. The four individual, spring-loaded modular
pattern controllers are mounted in the diffuser frame and position the leading edge of the pattern controllers near the
perforated face and flush with the ceiling for optimum performance. The engineered design maintains a tight, uniform
horizontal throw pattern from maximum to minimum cataloged air volumes, providing excellent performance in VAV
systems.
The 4340M is a square neck grille frame design, featuring full face pattern controllers, for surface mount installation in hard
ceilings. Discharge pattern can adjust to 1, 2, 3 or 4-way horizontal, before or after installation. Discharge pattern is
adjusted by dropping the perforated face and rotating the pattern deflectors. Diffusers are shipped from the factory with a
4-way discharge pattern.
FEATURES:
Hinged removable face plate with
quick-release spring latches.
Discharge pattern can be adjusted
to a 1, 2, 3 or 4-way horizontal pattern
before or after installation.
Discharge pattern is adjusted by
dropping the perforated face and
rotating the modular sections.
Frame is mechanically interlocked
for strength with hairline mitered
corners.

Balancing:
It is recommended that a commercially
available 'Flow Hood' is used for field
balancing. The airflow meter directly
reads average flow rate with great
accuracy at all volumes. It is a much
faster and more accurate alternative
to time consuming multiple velocity
readings, eliminating the use of Ak
factors and the calculations required
to convert the average velocity into
airflow.

CEILING DIFFUSERS
The Nailor Perforated Ceiling Diffusers have been designed to provide both the unobtrusive, smooth appearance
preferred by many architects and the high engineering performance required for use in heating and cooling applications.
They project a tight, uniform horizontal blanket of air over a wide range of air volumes and provide excellent performance
in variable air volume systems.
The 4330 Series features an extruded aluminum frame with hairline mitered corners that encapsulates the perforated face
providing a narrow, visible border within the T-Bar module. Four individual stamped pattern controllers mounted on the rear
of the diffuser face are easily field adjustable to suit the desired air pattern.

Balancing:
It is recommended that a commercially
available 'Flow Hood' is used for field
balancing. The airflow meter directly
reads average flow rate with great
accuracy at all volumes. It is a much
faster and more accurate alternative to
time consuming multiple velocity
readings, eliminating the use of Ak
factors and the calculations required to
convert the average velocity into
airflow.

CEILING DIFFUSERS
The Nailor 4330CB Curved Blade Diffusers provide the unobtrusive, smooth appearance preferred by many architects
with superior features and performance characteristics. Designed to maximize throw, this model features individually
adjustable, friction pivoted curved blade deflectors mounted directly under the neck. They project a tight, uniform horizontal
blanket of air over a wide range of air volumes and provide excellent performance in variable air volume systems.
The 4330CB Diffuser features an extruded aluminum frame with hairline mitered corners that encapsulates the perforated
face providing a narrow, visible border within the T-Bar module. The deflector blades can be adjusted to control both the
angle of discharge and hence throw from full horizontal to vertical in each direction and also damper the air volume. By
closing off the deflectors in one or more directions, directional control can also be achieved. The 4330CB is supplied with
a 4-way adjustable discharge pattern as standard but is also available with a factory supplied 1, 2 or 3-way adjustable
discharge pattern controller.

Balancing:
It is recommended that a commercially
available 'Flow Hood' is used for field
balancing. The airflow meter directly
reads average flow rate with great
accuracy at all volumes. It is a much
faster and more accurate alternative to
time consuming multiple velocity
readings, eliminating the use of Ak
factors and the calculations required
to convert the average velocity into
airflow.

CEILING DIFFUSERS
The Nailor Model 4310A Perforated Supply Diffusers have an all aluminum constructed design that combines a smooth
unobtrusive architectural appearance with the superior performance characteristics required by engineers. This diffuser is
suitable for MRI rooms.
The 4310A features a smoothly contoured die-formed backpan and wrap-around fixed perforated face. The round disc
pattern deflector provides a true 360 radial horizontal air pattern. A tight air pattern protects the ceiling against smudging,
providing excellent performance in VAV systems.
The Nailor Model 4310AR Perforated Return Diffuser is designed to match the supply model but omits the pattern
deflector. It is suitable for ducted return applications.

Performance Notes:
1. All pressures are in inches w.g. To
obtain static pressure, subtract the
velocity pressure from the total
pressure.
2. Throws are given at 150, 100 and
50 fpm terminal velocities, under
isothermal conditions.
3. NC (Noise Criteria) values are
based on 10 dB room absorption, re
10-12 watts. Dash () in spaces indicates
an NC level of less than 15.
4. Data derived from tests conducted
in accordance with ANSI/ASHRAE
Standard 70 2006.

Model 4360
The Nailor 4360 Series Perforated Face return air models are designed to match supply air models 4320, 4320CB, 4320F,
4320MR and 4320M in appearance and construction detail, less the air pattern controllers which are not required.
The 4360 Series is offered in two versions. One for ducted return applications which features the same backpan as the
supply air models with a neck for connection to flexible or rigid round duct or square duct. The other version features a
dedicated frame assembly which has a neck that is 2" (51) less than the ceiling module size. This unit maximizes free area
and may be used for ducted or ductless return air applications.
The 4365 model features a drop (extended) face panel that both matches in appearance the drop face supply models and
compliments tegular tile ceiling systems, allowing the perforated face panel to remain flush with the ceiling line.
FEATURES:
Round or square necks available.
Hinged, removable face plate with
quick-release spring latches.
Inlet collar has minimum 1 1/4" (32)
depth for easy duct connection.
Dropping the perforated face gives
access to the optional damper.

Airflow Measurements
1. Balancing factors are applicable
with or without dampers, providing
uniform airflow exists into diffuser.
2. Take velocity readings at a number
of locations on the inlet face (a
minimum of 4), while positioning probe
as shown above, one inch out from the
face.
3. Total the various velocity readings
and divide by the number of readings
taken to arrive at an average inlet
velocity (Vk in FPM).
4. Calculate the airflow (CFM) by
multiplying the average velocity by the
appropriate Ak factor.
Airflow (CFM) = Average velocity (Vk)
x Ak.

CEILING DIFFUSERS
Model 7500
The Nailor 7500 Series Diffusers have been specially designed to provide a versatile 'modular core' product which is
available in a comprehensive range of sizes and air capacities, providing optimum simplicity and flexibility for field adjustment
of the discharge air pattern. They maintain a horizontal ceiling pattern from maximum to minimum flow and make an excellent
choice for use in variable air volume systems.
The 7500 Series features four individual spring-loaded 'modular' pattern controllers mounted in the neck. They can be
adjusted before or after installation, to provide a 1, 2, 3 or 4-way discharge pattern by simply rotating one or more of the
pattern controllers which takes only a few seconds.
FEATURES:
Square neck is standard.
Round transition adaptors are
available (SR option).
Each diffuser features four
individually adjustable 'spring-loaded'
modular cores.
Simple adjustment for a 1, 2, 3 or
4-way horizontal discharge pattern
without the use of tools.

All diffusers are shipped with the standard 4-way pattern, but the air pattern can be simply field adjusted by rotating the
spring loaded pattern controllers.

CEILING DIFFUSERS
Model 61CC
The Nailor 61CC and 51CC Series Curved Blade Diffusers are similar in design and construction to the Nailor 61C and
51C Series Curved Blade Grilles with the addition of a modular sized panel to integrate with various types of ceiling
systems. Available with the choice of a 1, 2, 3 or 4-way discharge pattern.
They also feature individually adjustable friction pivoted curved blades on 1" (25) centers that positively control the airflow.
Blades are adjustable from the face, regulating the angle of discharge from a horizontal through to a full down-blow vertical
pattern as required. Blades can also regulate air volume as they are closed off.
Available in a comprehensive range of square duct sizes to suit a large range of air volumes, these diffusers, when adjusted
correctly, produce a tight horizontal ceiling pattern and work extremely well in variable air volume applications.
The Nailor 61CCD and 51CCD Series, available in a 1 or 2-way discharge pattern are similar to the above but incorporate
a set of rear vanes on 3/4" (19) centers that are individually adjustable, thus providing complete directional control and
airflow equalization.
FEATURES:
Extruded aluminum blades are
formed to an engineered curved and
streamlined cross-section. Formed
with tenons at each end to fit snugly
into side margin, friction loaded to
firmly hold deflection setting.
Adjustable angle of discharge from
horizontal to vertical.
Choice of one, two, three or four-way
discharge patterns.
Optional steel or aluminum opposed
blade dampers have a screwdriver
slot operator accessible through the
face of the diffuser.

Performance Notes:
1. Pressures are expressed in inches
of water gauge.
2. Throw values are given for terminal
velocities of 150, 100 and 50 fpm, with
a cooling temperature differential (T)
of 20F and are based on surface
mount units benefiting from the coanda
effect. The blade settings were set for
optimum discharge, parallel to the face
of the grille, that have the outer blades
closest to the frame set with an
opening of 1/8" (3) and progressively
wider spacing between blades away
from the frame. (Note: The throw
values may be increased or decreased
by as much as 20% by changing the
blade setting).
