Anatomy of an oil-free screw compressor!

Sep. 23, 2024

As a manufacturer of clean compressed air systems, we provide pure oil-free compressed air with high cleanliness, leading the future direction of the air compressor industry and providing

 customers with high-quality products and the best user experience. Our water-lubricated oil-free screw air compressors, as well as our unique all-stainless steel alloy host and stainless steel 

system are well-known in the industry.

The main engine has the longest-life stainless steel alloy rotor, and the rotor meshing pair is produced using the patented technology of flying parts. The contact stress between 

the rotors is very small, thereby reducing internal leakage and rotor compounding.


During the working process of the rotor, pure water is sprayed between the rotors to cool the air, thereby purifying the air. The dust and heavy metal content are minimal.

 At the same time, the z-shaped rotor and the pure water between the rotors will form a good water film seal,

 so that the system efficiency reaches more than 95%. Fully realize energy saving, oil-free compression system, no oil, no waste oil treatment, and can extract the purest compressed air. 

The water-gas mixture compressed by the main engine enters the water-gas separation cylinder and is mechanically separated into compressed 

air and pure water. Because the system temperature is below 45 degrees, the water content of the compressed air is less than 80 grams per cubic meter.

The compressed air on the separator passes through the minimum pressure valve and enters the exhaust hole for discharge. The pure water at the bottom of the separator passes through 

the filter to remove impurities and bacteria in the 

water. After cooling, the water enters the compression host again for the second compression cycle. The water-lubricated 

oil-free screw air compressor realizes automatic water change and reduces labor intensity. The centrifugal fan is noisy and has high wind pressure.


The water-cooled plate heat exchanger is highly efficient and corrosion-resistant. The cloud network can realize 24-hour network wireless interconnection monitoring, remote connection 

of multiple machines, remote minister warning machine alarm, and timely reminder of normal maintenance and maintenance. 

The water-lubricated oil-free screw air compressor is an energy-saving, environmentally friendly and stable product among oil-free compressors. It is widely used in photovoltaic 

chemical industry, food, textile, mechanical electronics, medicine, bioengineering and other industries.
