Low noise oil free electric portable air compressor

Technical parameter of the oil free screw air compressor 

Detail about the parts of the oil free screw air compressor 

Advanced technology :Owning Core technology patent(United States, Britain, Japan invention patent)

a.The fourth generation Air End -China's first manufacturer adopting high-end materials(copper alloy)

b.Extraordinary design,Low rotation speed ,Low temperature rise

c.Energy-saving control system

1)Using pure water for lubrication and cooling, the body's internal components combination is made of special material-copper alloy,never corrosion;
2)Always having pure water circulating in its systerm and the systerm will automatically change water at set time to ensure the quality of the water
line and the body temperature is not higher than 50 degrees, so the water in the body will not suffer water scale problem;
3)Adopting high-end special bearing, silicone bearing, so there is no any problem using pure water for lubrication , high efficiency, lower noise,less
shaft bearing combination;
4)Directly sprayed pure water in the body, because water has higher calorific value, so the compression chamber is almost in isothermal compression
state, energy saving;
5)Direct-driven between body and motor,Lower rotation speed ,below 3000 RPM, No overdrive gear,longevity and low maintenance.
6)Apart from the air filter,pure Water will wash and filter the impurities in the air ,ensuring the outlet clean air, greatly reduce the load and supplies
expense of post processing equipment .
