H. BLOWER (Squirrel Cage Fan) MOTOR ASSEMBLY

1. Blower (Squirrel Cage) Motor Description

The AD-410 uses an 22-1/4 inch diameter, blower (squirrel cage fan) wheel. It spins (turns) in a counterclock-

wise (CCW) direction when looking at the back of the blower housing.

The blower (squirrel cage fan) shaft is mounted in two (2) 1-3/4" diameter pillow block bearings, and the

shaft is driven by two (2) B-section V-belts connected to the blower motor).

The blower (drive) motor is mounted on an adjustable base. The motor position can be easily adjusted so

that the proper tension can be maintained on the V-belts.
