Direct driven common screw air compressor ?is a type of?gas compressor, such as an?air compressor,?that uses a rotary-type positive-displacement mechanism. They are commonly used to replace?piston compressors?where large volumes of high-pressure air are needed, either for large industrial applications or to operate high-power air tools such as?jackhammers?and impact wrenches.The gas compression process of a rotary screw is a continuous sweeping motion, so there is very little pulsation or surging of flow, as occurs with piston compressors.Specifications:Brand:HandeModel:HD7.5APower:5.5kwAirend:Hanbell/BSCCapacity:0.5~0.8 m3/minPressure:7~12.5barElectricity:380V/50HZProtection class :IP54 only for motorDriven mode:BeltStarting Mode:Y-â–³ StartDimension:760*660*880mmNet weight:175kgsNoise:Low noiseWarranty:1 year for whole machine, 2years for airend.Shipping port:Shengzhen YantianPacking:Inner PE film,outside wooden caseAdvantages?
