F4-72 Type (Type C) Fiberglass Centrifugal Ventilation Fan
F4-72 Type (Type C) Fiberglass Centrifugal Ventilation Fan
| Parameter
The F4-72 (Type C) FRP centrifugal fan features an impeller driven by a motor via a V-belt, with either a water-cooled or oil-cooled bearing housing. This design helps minimize corrosion of the motor, reduces mechanical wear on gears and bearings, and lowers the motor’s operational load—ultimately extending the fan’s service life. Boasting high strength, lightweight construction, excellent resistance to aging, superior corrosion protection, low noise levels, and smooth operation, this fan series is widely regarded as an ideal choice for corrosive environments. It finds extensive application in industries such as chemical processing, electroplating, oxidation processes, power plants, laboratories, printed circuit board manufacturing, and environmental protection equipment—anywhere where corrosive gases are present.
