FAN
BOARD:
All motors, with internal thermal temperature
cutout above 140°C, are permanent
split-capacitor, three speed, tap wound,
and induction type for maximum efficiency.
Motors have permanently lubricated sealed
sleeve bearings and all direction, vibration
isolating mountings to ensure vibration
free operation and minimum noise. Motor
wiring is connected to the junction box
in flexible metal conduit. All motors
are factory run tested and tested in the
completed unit prior to shipment.
All unit sizes have double motor shaft
extensions. Fan wheels, mounted directly
on the motor extension shaft, are the
centrifugal, forward curved, multi-blade,
double-width, double-inlet type made of
galvanized steel. Fan housings are made
of galvanized sheet steel. For ease of
servicing, the fan board can be simply
removed form the unit by loosening the
fasteners.
