According to user requirements made corrosion proof type. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - centrifugal fan blower] work, power machine (mainly motor) driven impeller rotating fan in the volute casing, impeller air through the suction port from the center Department inhalation. Due to the dynamic action of the blades on the gas, the gas pressure and speed can be improved, and the centrifugal force along the road leaves the cabinet Shuaixiang discharged from the exhaust port. Because the gas flow in the impeller is mainly in the radial plane, so called fan runoff. Centrifugal fan impeller and casing composed mainly by wind chassis, small fan impeller is mounted directly on the motor, the large fan by coupling or connection with the motor pulley. Usually unilateral centrifugal fan inlet, with a single-stage impeller; flow can be bilateral intake, with two back to back impellers, also known as double-suction centrifugal fan. Wind chassis, fan Langfang, Tianjin Jinzhong Ji fan manufacturers are provided by Tianjin Jinzhong Ji HVAC purification equipment.
