4-72 Centrifugal Fan:

The 4-72 centrifugal fan is designed to convey air and other non-self-igniting, non-hazardous to humans, and non-corrosive to steel gases. The gas should not contain viscous substances, and the dust and hard particles contained should not exceed 150mg per cubic meter. The gas temperature should not exceed 80°C. This fan features excellent aerodynamic performance, smooth operation, low vibration, high efficiency, and long service life.

It is widely used for indoor ventilation in industrial and mining enterprises, large buildings, hotels, and restaurants. The B4-72 explosion-proof centrifugal fan mainly consists of an aluminum impeller, casing, air inlet, and explosion-proof motor. It can be used for ventilation of flammable volatile gases only. Its performance and installation dimensions are the same as those of the 4-72 model.
