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