Fiberglass centrifugal fan, as the name suggests, is a type of centrifugal fan with a casing made of fiberglass anti-corrosion material. Its working principle is that when the motor rotates to drive the fan impeller to rotate, the gas between the blades in the impeller also rotates and is thrown out under the action of centrifugal force. The gas flow rate increases, causing the gas to convert kinetic energy into static pressure energy in the flow. Then, with the increase of fluid pressure, the static pressure energy is converted into velocity energy, and the gas is discharged through the exhaust port. A certain negative pressure is formed in the middle of the impeller. Due to the negative pressure at the inlet, the external gas is immediately replenished under the action of atmospheric pressure. Under the continuous rotation of the impeller, the gas is continuously discharged and replenished, thus achieving the purpose of continuous blowing.

Under the same power, wind pressure and air volume are generally inversely proportional. At the same power, when the air pressure is high, the air volume will be relatively low, while when the air volume is high, the air pressure will be lower, so as to fully utilize the efficiency of the motor.
