All commercially available version galvanized square suction fan structure is basically the same technical parameters. The main models are 1380 * 1380 * 400mm1.1 kW, 1220 * 1220 * 400mm0.75 kW, 1060 * 1060 * 400mm0.55 kW, 900 * 900 * 400mm0.37 kilowatt four models. All galvanized square suction fan speed version are 450 rev / min for 4-pole motor 1400 rev / min, motor protection class IP44, Class B insulation. Individual smaller size due to the small amount of wind suction fan, noisy, inefficient ventilation lost significance as a suction fan, not described here. Relatively large suction fan ventilation higher efficiency, more energy efficient. FRP flared suction fan belts from different transmission structure is divided into two kinds of style and straight knot. HTFC series of fire ventilation (dual) tank centrifugal fan is divided into A and B are two types of farming fan wholesale prices, A motor mounted on the outside of the box fan breeding sales price for exhaust fan fire; B-type motor cabinets installed in the fan for ventilation. A type fire tank centrifugal blower motor installed in the box outside the breeding fan specifications, with separate temperature exhaust system isolation, ensuring fans at 300 ℃ high temperature, more than 60 minutes of continuous operation. By the "National Fire Equipment Quality Supervision and Inspection Center" qualified, the performance of the leading domestic level. FRP fan culture, Fuyang farming fans, Qingzhou Minhua Qingzhou temperature control equipment supplied by Chinese citizens thermostat plant.
