F4-72-A Centrifugal Fan

The 4-72 centrifugal fan is a high-efficiency and energy-saving centrifugal fan. Its wing-type blades, curved impeller front plate, and conical inlet diffuser contribute to excellent aerodynamic performance. The fan has been widely used for many years in China’s economic construction and remains popular. The fan offers four transmission types: A, B, C, and D. Type A connects the impeller directly to the motor; Type B uses a belt drive with the pulley located between the two bearings; Type C also uses a belt drive, with the pulley mounted at the outer side of the bearing; Type D connects the impeller to the motor via a coupling.

Applications:

The F4-72 corrosion-resistant centrifugal fan is suitable for installation in chemical plants, laboratories, basements, swimming pools, etc., for conveying corrosive gases, acidic or alkaline gases, and high-humidity gases.

The B4-72 explosion-proof centrifugal fan is specifically designed for explosion-proof applications. It is suitable for use in fuel and gas boiler rooms, high dust concentration workshops, oil depots, gas storage stations, and warehouses for hazardous materials. It can transport flammable, explosive, and volatile gases.
