Oil-free Air Compressor
EP is always working for high technology of air compressor. After developing of water lubrication oil free screw air compressor, we continue develop the two-stage compression of 4.0 Mpa oil free screw air compressor requirements such as for example JB/T 11882-2014 . Oil-free scroll surroundings compressor is a new design and developed by HL which differs from any others scroll air compressor in the globe. HL scroll air compressor more sensible structure, good heat dissipation, longer using existence, better stability, air-end 2 years warrantly and also the only one who can manufacture 1.2Mpa scroll air compressor in the global.
Oil-totally free scroll air compressor features :
1、High precision & inventive design air-end, longer service time and 2 years warranty
2、Using permanent magnet engine,compressor efficiency is usually improved 10%
3、Motor is connected with air-end directly, without 
belt,coupling,no require adjustment, super low noise
4、PLCcontroller display discharge temperature, pressure,procedure time, maintenance stay and fault alarm,etc.
Working principle of oil-free scroll air flow compressor
Air compressor procedures which is noticed by the motion of rotor and stator. The air is sucked From the medial side of air-end, rotor seals the compression chamber and atmosphere is compressed gradually along with rotor movement and compression chamber become smaller sized. Compressed surroundings discharged from the guts of stator. This is a continues processes, the discharged compressed air flow Is smooth and no fluctuation.
The movement of rotor refer figure 1-4 (suction-compression-exhaust).The suction air is gradually Compressed in the smaller and smaller compression chamber due to rotor and stator motion, at last the compressed air is discharged from the center discharge hole.
We is a leading manufacturer of industrial air compressor china manufacturers, oir free air compressor china suppliers and screw atmosphere compressor china spare parts.Located in China, our item lower noise air flow compressors,Oil-free screw atmosphere compressor range signifies the most comprehensive portfolio of compressed air flow equipment offered for a large number of applications in the Oil, Textile, Food, Marine, etc. industries.
