Features:

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.
