DRIVES
Transmission of power from the motor
to the fan is provided by means of a set
of pulleys and matching V-belts. The
pulleys are taper locked to the fan and
motor shaft. PM-series air handling units
are equipped with the optimized pulleys
and belts, which are sized and preinstalled by factory. Optimal selection of
drives pulleys and proper installation
will ensure that the fan operate at the
required designed speed and at same
time help to prolong fan and motor
bearing life. Belt guard is available as
option to provide extra safety.
