4-2X79E, 4-79A type centrifugal fan
4-2X79E and 4-79A centrifugal fans can transport air and other unnatural, harmless and corrosive gases to steel. Viscous substances are not allowed in the gas, and the dust and hard particles contained are not more than 150mg/m3. The gas temperature shall not exceed 80℃. The fan has good aerodynamic performance, and the impeller and belt are strictly corrected by static and dynamic balance, so it features stable operation, small vibration, high efficiency and long life. Widely used in industrial and mining enterprises, large buildings, hotels and restaurants for indoor ventilation and smoke exhaust.
