The 4-09 series large-flow centrifugal fan is the earliest used fan in China, and it is also the most commonly used fan.
Suitable for conveying clean air or light materials at normal temperature, most commonly used in industrial furnaces for air supply, light particle/powder/crush/fiber transportation, air drying/cooling of materials, ventilation and smoke exhaust, and other areas.
No viscous substances are allowed inside the gas, and the dust and hard particles contained in the gas are larger than 150 mg/m3, and the gas temperature does not exceed 80°C.
