4-72 centrifugal fan can convey air and other non-self-igniting gases, which is harmless to human body and non-corrosive to steel materials. The gas shall not contain toxic substances, and the dust and hard particles contained shall not exceed 150mg/m2. The gas temperature shall not exceed 80ºC. It has good aerodynamic performance, balance, small vibration, high efficiency and long life. It is widely used in industrial and mining enterprises, large buildings, hotels, restaurants and other indoor ventilation, air change and operation. B4-72 is an explosion-proof centrifugal fan, which is mainly composed of centrifugal fan, impeller shell, explosion-proof motor, etc., and can be used for ventilation of flammable and volatile gases. Its performance and base size are the same as 4-72. F4-72 is an anti-corrosion centrifugal fan, which is mainly composed of glass fiber reinforced plastic (or stainless steel) impeller shell, air inlet, etc. and motor, etc., for conveying corrosive gases. Its performance and base size are the same as 4-72.
