Fiberglass blowers are recommended for fume hood exhaust systems in moderate to highly corrosive conditions. The housing is made from molded fiberglass-reinforced polyester for durability and long life. Impellers are made of injection-molded polypropylene to resist corrosive atmospheres.

Both blowers have a dry powder epoxy-coated base and weather cover for protection in extreme weather. Sheaves are adjustable to allow for air volume adjustment. Self-adjusting gravity belt tightener ensures consistent performance because belt is held taut by weight of motor. Motor mount keeps the motor in place should the belt ever fail.

Spectrum Blowers do not use belts, therefore use less energy and are suitable for all applications.
