FRP centrifugal fan is made of FRP material fan, also known as anti-corrosion centrifugal fan, generally FRP centrifugal fan can be used in the occasion of corrosive gas, emitting corrosive gas. The gas it transports is not allowed to contain viscous substances, dust and hard particles less than or equal to 150mg/m3, gas temperature is less than or equal to 60 degrees, relative humidity is less than or equal to 100%, high temperature places are not suitable for frP centrifugal fans.

FRP centrifugal fans are widely used, it can be used in chemicals, electroplating, oxidation, power plants, laboratories, circuit boards, environmental protection equipment and other occasions containing corrosive gases. 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, using a molded FRP impeller, the bending strength is not less than 196Mpa, each section is sleek and excessive, the appearance is smooth, and there are no defects such as cracks, gaps, burrs and so on.

The overall effect is good, the fan does a static balance test, according to the "rigid rotor balance accuracy", the grade is G6.3, the leaf tip is 30mm from the inner wall gap of the wind drum, and the error is not greater than ±10mm. The fan aerodynamic is reasonable, the air volume is large, the noise is low, the efficiency is high, the corrosion resistance is thrown out, and these gases are thrown out under the action of centrifugal force, and the gas flow rate increases, so that the kinetic energy is converted into static pressure energy in the flow, and then with the pressure of the fluid, the static pressure energy is converted into speed energy.
The gas is discharged through the exhaust port, and a certain negative pressure is formed in the middle of the impeller, because the inlet is negative pressure, so that the external gas is immediately replenished under the action of atmospheric pressure, and the gas is continuously discharged and replenished under the continuous rotation of the impeller, so as to achieve the purpose of continuous blowing. Under the same power, the wind pressure and air volume are generally inversely proportional, under the same power, the wind pressure is high, the air volume will be relatively low, and the air volume is large, the wind pressure will be lower, so as to make full use of the power efficiency of the motor.
