Working principle
The compression process of the oil-free scroll is realized by the rotating motion of the stationary scroll and the movable scroll.
The air enters from the outside of the main engine, and after the air is sucked in, the moving scroll closes the air inlet. With the rotation of the movable scroll, the air is continuously compressed, and the compressed oil-free air is sent from the center of the stationary scroll. This process is repeated continuously to ensure that the discharged compressed air is continuous and without fluctuation.
Features and advantages
100% oil free
It can be used in any industry, especially suitable for users who require high oil content in compressed air.
Run quietly
Scroll air compressors operate with extremely low noise and a healthier working environment.
Easy to install
It occupies a small area and can be installed near the gas point, thereby reducing the installation of compressed air pipe network and effectively reducing the installation cost of the pipe network.
Simple maintenance
There is no need to replace or add lubricating oil, only a small amount of consumables need to be replaced regularly, and the maintenance cost is low.
Zero emission
Only condensate is discharged, no harmful substances are discharged, in line with sustainable development goals.

Clean oil free compressed airAdopt 74 degree conicity dry seamless, more reliable seamless, eliminate air leakage. Not just compression process is oil free, but also on the afterward transportation adopt stainless steel pipe, stainless steel check valve, stainless steel air receiver(for air receiver mounted), ensure the quality of compressed air.
High efficiency scroll air end
Adopt the advanced oil free scroll airend, reliable bearing and grease, make sure the reliability and long life-span of airend, high precise machine for motivated scroll, fixed scroll and housing, ensure high efficiency of airend. Reliable seamless material, ensure compression chamber and lubricated transmit 100% be separate, ensure compressed air is oil free.
High Reliability
Cooling fan adopt integrated centrifugal impeller, low noise, high cooling air pressure, high cooling air, ensure the cooling air is enough, ventilation fan adopt silence axial fan, ensure the heat inside of cabinet could be eliminated in time. Heat exchange has been increased 20%-30%, anticorrosive treatment inner structure, after strict testing, ensure the exhausting air less than environment temp.+10-15ºC, reduce the burden of downstream equipment. Adopt direct driven, not belt driven, improve transmission efficiency & reliability, reduce the maintenance cost of changing belt.
