4-68 centrifugal fan air volume from 600-240000 cubic meters/hour, wind pressure 250-3800 Pascal, Power: 0.55-220kw, low-pressure gale volume, there are ordinary, anti-corrosion type, explosion-proof type, high temperature type 4 specifications. Motor Direct, belt drive and other ways

. usage

Type 4-68 centrifugal ventilator is generally used for ventilation and ventilation of factories and large buildings, can be used as input gas, but also as an output gas, the fan may transport air or other non-spontaneous combustion, not easy to explode, non-volatile, harmless to the human body, non-corrosive to steel gas, and the gas must not have viscous substances, The dust and hard particulate matter contains no more than 150mg/m3, and the gas temperature must not exceed 80 ℃.

Structural features

The №2.8~6a of type 4-68 fan is mainly composed of the impeller, the chassis, the air inlet and other parts of the distribution machine directly linked.

№6.3~20 In addition to the above parts there are transmission parts:
Impeller: 12 pieces of rear tilt wing blade welded in the middle of the arc cone type wheel cover and plate roulette, are made of steel plate, and by static balance correction and overspeed operation experiment, good air performance, high efficiency, smooth operation.
