CMN series Oil-free scroll air compressor

Oil-free scroll air compressor china

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 standards such as JB/T 11882-2014 . Oil-free scroll air compressor is a new design and developed by HL which is different from any others scroll air compressor in the world. HL scroll air compressor more reasonable structure, good heat dissipation, longer using life, better stability, air-end 2 years warrantly and also the only one who can manufacture 1.2Mpa scroll air compressor in the global.

Oil-free scroll air compressor features :

1、High precision & inventive design air-end, longer service time and 2 years warranty
2、Using permanent magnet motor,compressor efficiency is improved 10%
3、Motor is connected with air-end directly, without belt,coupling,no need adjustment, super low noise
4、PLCcontroller display discharge temperature, pressure,operation time, maintenance remain and fault alarm,etc.

Working principle of oil-free scroll air compressor

Air compressor processes which is realized by the movement of rotor and stator. The air is sucked From the side of air-end, rotor seals the compression chamber and air is compressed gradually along with rotor movement and compression chamber become smaller. Compressed air discharged from the center of stator. This is a continues processes, the discharged compressed air 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 movement, 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 air compressor china spare parts.Based in China, our product lower noise air compressors,Oil-free screw air compressor range represents the most comprehensive portfolio of compressed air equipment offered for thousands of applications in the Oil, Textile, Food, Marine, etc. industries.
