· Precision air end

High precision, stiffness and durable square air-end ensures pressure can reach to 174PSI.

· Low discharge compressed air temperature

Which near the ambient temperature after cooled by the individual fan to ensure the low pressure dew point.

· Super quiet

Smart structure and advanced soundproof casing to reduce the noise to 49dB(A).

· Simple and convenient

Air-end set can be matched with any devices which need compressed air.

· Oil-free

No need any lubrication oil. Oil grease is added one time per year.

· Low consumable cost

Only air filter and sealing element are consumables.

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
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.
