 Totally
enclosed, thermally protected auto-reset, heavy-duty motors have
sealed pre-lubricated ball bearings. The FP series fans use the
best U.S.A. made motors available. All motors are dual voltage
(120 and 240 VAC), except two-speed fans which are only 240 VAC.
Quiet running polypropylene fan propellers have replacement
blades. The polypropylene propellers stay cleaner than other
manufacturer's, and they are perfectly balanced.
Nickel plated motor mounts have a radial design for less air
restriction. The motor mounts also serve as a rear blade safety
guard.
Osborne RTM-Glas™ fiberglass orifice housings are rigid and
will not warp or heat-sag like cheaper poly housings, even after years
of operation. Agri-Aide housing maintain a perfect orifice for the
propeller. The rugged design is impact resistant and can be easily
cleaned, providing a lifetime of service.
