PP Centrifugal Fan

The 4-72PP fan is currently an ideal corrosion-resistant ventilation equipment for industrial production centers, featuring excellent properties such as high strength, strong corrosion resistance, stable operation, and low noise. After years of meticulous design and continuous improvements by our company's technical team, the performance and quality have been increasingly perfected, widely replacing fans made of other corrosion-resistant materials.The principle of the PP plastic corrosion-resistant centrifugal fan: When the motor rotates and drives the fan impeller to spin, the gas between the blades of the impeller also rotates. Under the action of centrifugal force, this gas is thrown out, increasing the gas flow velocity and converting kinetic energy into static pressure energy during the flow. Then, as the fluid pressure increases, the static pressure energy is converted back into velocity energy, and the gas is discharged through the exhaust outlet. Meanwhile, a certain negative pressure is formed in the middle of the impeller. Due to the negative pressure at the inlet, external gas immediately replenishes under atmospheric pressure. With the continuous rotation of the impeller, gas is continuously discharged and replenished, achieving the purpose of continuous air blowing. Under the same power, wind pressure and air volume are generally inversely proportional. With the same power, higher wind pressure results in relatively lower air volume, while greater air volume leads to lower wind pressure, thus fully utilizing the motor's power efficiency.
