    F4-72-AType FRP Centrifugal Fan (Direct Motor) is made of fiberglass composite material with reference to the performance parameters of metal 4-72-A centrifugal fan. This series of fans can transport corrosive gases containing acid, alkali and chemical components. The conveyed gas is not allowed to contain viscous substances, contained dust and hard particles (150m to m3, gas temperature ≤60℃, relative humidity ≤100%. This series of fans have high strength, light weight, not easy to age, and good corrosion resistance. , Low noise, stable operation, etc., is an ideal general-purpose anti-corrosion fan. This series of fans are widely used in chemical, electroplating, oxidation, power plants, laboratories, circuit boards, environmental protection equipment and other places containing corrosive gases .


    1. Good ventilation effect: F4-72-A glass fiber reinforced plastic centrifugal fan has good air extraction effect, which is very suitable for pipe exhaust or air supply;

    2. Corrosion resistance: It can resist acid and alkali corrosion and has a long service life.

    3. Low noise: F4-72-A glass fiber reinforced plastic centrifugal fan adopts reasonable impeller angle design according to aerodynamics, there is no mechanical friction during operation, and reasonable blade shape line minimizes noise; F4-72-A glass fiber reinforced plastic centrifugal fan The noise produced by the fan is high-frequency noise, as long as there are obstacles, it can be soundproof.

    4. Smooth operation: The optimized design of the impeller reduces the axial force to the minimum, and there is an efficient impeller, and the static and dynamic balance correction, so that the whole machine runs smoothly. Without any vibration reduction device, the bearing The amplitude is relatively small.

    Advantages and disadvantages of direct connection:

    Advantages: saving parts, fewer vulnerable parts, reliable performance. The fan shaft has no lateral force, and the transmission power can be large.

    Disadvantages: Directly connected to the motor, its impeller speed is equal to the motor speed. Direct connection is generally suitable for fans with relatively small air volume and pressure, with low optional speed.
