4-72, B4-72, F4-72-type centrifugal fan

Introduction to performance

    &Nbsp; 4-72 type centrifugal fan for conveying air and other natural, harmless to human body and the steel non-corrosive gases. Viscous substances are not allowed in the gas, which are rigid, and the dust particles no larger than 150mg/M3. gas temperature must not exceed 80 ℃. The fan has a good aerodynamic performance, operation is smooth, small vibration, high efficiency, long life and other characteristics. Widely used in factories, large buildings, hotels, restaurants and other indoor ventilation.

&Nbsp;     B4-72 for explosion-proof type centrifugal fans, mainly composed of aluminium impellers, casing, inlet and other components with explosion-proof motor, as flammable volatile gas ventilation purposes, its performance and installation dimensions with type 4-72.

&Nbsp;     F4-72-type corrosion type centrifugal fan, mainly made of stainless steel (or GRP) made from impeller and casing, inlet and other components with motor, can be used to transport corrosive gases, its performance and installation dimensions with type 4-72.
