The American Coolair NBF48 fan is built to withstand the harsh conditions common to holding sheds and give years of heavy duty, trouble-free service. Its rugged, belt-driven construction operates in any position, and it has permanently lubricated ball bearings. The fan is available with single- or two-speed totally enclosed motors.
