9-20-11 High Pressure Centrifugal Fan
9-20-11 High Pressure Centrifugal Fan is generally used in forging furnaces and forced ventilation under high pressure in conveying air, non-corrosive, non-prolific gas containing no adhesive matters. The medium temperature should not exceed 50℃, and the dust content and hard particles in the medium shall not exceed 150mg/m3.

The medium temperature should not exceed 50℃, and the dust content and hard particles in the medium shall not exceed 150mg/m3.
Key Advantages:
9-20-11 No. 4, 5, 6, 7, 8, 10, 12, 14, 16 fans are all directly driven by motors. Considering the high rotating speed of main shaft, the bearing base is relatively low and touches the cement foundation base in order to minimize blower vibration. For driving mode, No. 4-6 fans apply Type-A non-bearing box design and direct motor driving. No. 7-16 fans apply Type-D overhanging support system supported by rolling shaft and driven by flexible coupling and motor.
9-20-11 blower’s impellers have 12 front-curved vanes with outlet height of 30° and highest peripheral speed of 125m/s.
