Centrifugal fan is a machine that relies on input mechanical energy to increase gas pressure and transport gas. It's a fluid machine that drives. Widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings for ventilation, dust removal and cooling; Ventilation and air intakes for boilers and industrial furnaces; Cooling ventilation in air conditioning equipment and household appliances; Drying and selection of grains; Aeration and propulsion of wind tunnel sources and hovercraft.The centrifugal fan is composed of a shell, a main shaft, an impeller, a bearing transmission mechanism and a motor.
4-72 centrifugal fans can transport air and other non-spontaneous combustion and non-corrosive gases that are non-corrosive to steel. No viscous substances are allowed in the gas, and the dust and hard particles contained in the gas do not exceed 150mg/m3. The gas temperature must not exceed 80 °C.
4-72 centrifugal fan has good aerodynamic performance, balanced operation, small vibration, high efficiency and long life. Widely used in industrial and mining enterprises, large buildings, hotels, restaurants and other indoor ventilation.
B4-72 explosion-proof centrifugal fan is mainly composed of aluminum impeller, shell, air inlet and explosion-proof motor, which can be used for ventilation of flammable and volatile gases.
F4-72 corrosion resistant centrifugal fan is a kind of anti-corrosion centrifugal fan. It is mainly composed of stainless steel (or FRP) impeller, housing, air intake and other components and motor. Can be used to transport corrosive gases.
