The centrifugal fan can transport air and other gases that are non-spontaneous, harmless to the human body, and non-corrosive to steel. No viscous substances are allowed in the gas, and the dust and hard particles contained should not be larger than /. The gas temperature must not exceed ℃. The fan has good aerodynamic performance, and the impeller and belt have undergone strict static and dynamic balance correction, so it has the characteristics of smooth operation, small vibration, high efficiency, and long life. It is widely used in indoor ventilation and smoke exhaust in industrial and mining enterprises, large buildings, hotels and restaurants.
