Compressor:
1- Availability
Compressed air system components are extremely durable and can not be
damaged easily. Compared to electromotive components, pneumatic components
are more durable and reliable.
3- Simple design
The designs of compressed air system components are relatively simple. They
are thus more suitable for use in simple automatic control systems.
2. The advantages of Compressed air systems
4- Safety
Compressed air systems are safer than electromotive systems because they can work
in inflammable environment without causing fire or explosion. Unlike electromotive
components, pneumatic components do not burn or get overheated when overloaded.
5- Environmental friendly
The operation of compressed air systems do not produce pollutants. The air released
is also processed in special ways. Therefore, pneumatic systems can work in
environments that demand high level of cleanliness.
6- Economical
The compressed air system components are not expensive, the costs of pneumatic
systems are quite low. Moreover, the cost of repair is significantly lower than that of
other systems.
3. The Limitation of Compressed air systems

5.1. Compressed Air System Supply Side
maintain constant system pressure and manage the interaction between system
components.
Air filters and air dryers: remove moisture, oil and contaminants from the
compressed air.
Compressed air storage: can also be used to improve system efficiency and
stability.
use device.
5.2. Compressed Air System Demand Side
The demand side includes distribution piping, secondary storage and end use
2. Reduces wasted air from leakage and drainage and utilizes compressed air
Distribution piping systems transport compressed air from the air compressor to
the end use point where it is required. Compressed air storage receivers on the
compressor.
Inter-stage Coolers: Reduce the temperature of the air before it enters the
next stage to reduce the work of compression and increase efficiency. They
exits the compressor system. If this moisture is not properly removed, the
Distribution system The piping distribution system not only controls how
the air gets from the compressor room to the tools, it is a major factor in the
pressure increases leak rates, another major source of waste, thus the waste
Valves:
• Directional control valves ensure the flow of air between air ports by
• Flow control valve is a valve that controls the flow of air. Examples
There are three basic types of air compressors which are used in compressed
air systems:
Reciprocating
Rotary Screw
Rotary Centrifugal
Method of cooling
Drive method
