Our oil-free screw air compressor stands out in the market with its unique features and advantages which include:
The CM15B(F) oil-free screw air compressor is designed without a trace of lubricating oil. It adopts pure water to clean the acidic and alkaline substances in the compressed air, making it more pure and clean. This eliminates the need for cooling oil in the mainframe jacket.
All pipelines of our compressor are made of 304, 316 stainless steel materials or corrosion-resistant materials. With the adoption of equal speed direct connection technology between the motor and the main engine, the highest speed of the main engine does not exceed 2980 rpm/min. This ensures a longer service life for the bearing and rotor.
Our compressor uses direct water spray cooling rotor and cavity, achieving higher isothermal compression efficiency. It adopts dual compression cavity technology, a rotor with two compression cavities, surpassing two-stage compression. There is no need for intermediate cooling, reducing power consumption loss.
The daily maintenance of our compressor only requires the replacement of the air filter cartridge and water filter cartridge. This reduces the overall operating and maintenance costs.



The oil-free screw air compressor operates using a pair of main screws, namely the pressure screw and the rotating screw, to complete the compression process. These screws are usually made of high-strength alloy steel and have an accurate helical shape. As the screws rotate, the working chamber gradually expands, allowing external air to enter the working chamber through the suction port. Once the air enters the working chamber, the rotation of the screws causes the working chamber to gradually shrink. This shrinkage increases the compression ratio of the air, thereby increasing the air pressure. During this process, the air is compressed and pushed to the outlet of the machine. The compressed air generates heat during the compression process, so a cooling system is needed to reduce the temperature. At the same time, to ensure air quality, the compressed air needs to be cleaned through a filter system to remove potential contaminants and particles.

The CM15B(F) oil-free screw air compressor is versatile and can be used in various industries such as:
The oil-free air compressor provides an oil-free air supply, avoiding the risk of oil contamination. It is suitable for pneumatic operations, packaging, and processing in the food and beverage industry.
The oil-free air compressor can provide oil-free, sterile air, suitable for the operation of operating rooms, laboratories and other medical equipment in hospitals.
The oil-free air compressor can provide oil-free, sterile air that meets pharmaceutical standards, suitable for pneumatic conveying, packaging and sterilization in the pharmaceutical process.
The oil-free air compressor provides a clean air supply, preventing oil contamination damage to electronic components. It is suitable for applications in the electronics industry such as pneumatic tools, electronic component blowing and cleaning.

Our company's full range of products has passed the German TUV class 0 oil-free certification, CE certification, ISO9001 certification, TS16949 certification. We are the first domestic enterprise to use water for internal cooling and lubrication of high-end screw compressors. We have also pioneered the introduction of a secondary compression high-pressure micro-oil screw compressor with a pressure of 4.OMPa. Furthermore, we have developed the world's first 4.OMPa pressure oil-free screw compressor and the world's first 1.25MPa pressure oil-free vortex compressor.
