Our CM200BV is a truly oil-free screw air compressor. The main engine doesn't contain any lubrication oil, eliminating the need for jacket cooling oil. It uses pure water to cleanse acidic and alkaline substances in the compressed air, making it purer and safer for various applications.
All pipelines of our compressor are made of durable 304, 316 stainless steel or corrosion-resistant materials. The adoption of equal speed direct connection technology between the motor and the main engine keeps the maximum rotation speed below 2980rpm/min. This design enhances the service life of the bearings and the rotor.
The CM200BV uses direct water spray to cool the rotor and the chamber, making the isothermal compression efficiency higher. The unique double compression chamber technology, with one rotor and two compression chambers, surpasses two-stage compression, reduces the need for intermediate cooling, and minimizes power consumption loss.
Regular maintenance of the CM200BV only requires the replacement of the air filter and water filter elements, significantly reducing maintenance costs.



The oil-free screw air compressor uses a pair of main screws, the air pressure screw, and the rotating screw, for the compression process. These screws, typically made from high-strength alloy steel, have a precise helical shape. As the screws rotate, the working chamber between them gradually expands, drawing in external air through the intake. This air is then compressed and pushed towards the compressor's outlet. The heat generated during this process is managed by a cooling system. Meanwhile, a filtration system ensures the quality of compressed air by removing potential pollutants and particles.


The oil-free air compressor provides an oil-free air supply, eliminating the risk of oil contamination. It is suitable for pneumatic operations, packaging, and processing in the food and beverage industry.
Our oil-free air compressor can provide oil-free, sterile air, suitable for operation rooms, laboratories, and other pneumatic operations in hospitals.
The oil-free air compressor can provide oil-free, sterile air that meets pharmaceutical standards, suitable for pneumatic transport, packaging, and sterilization during pharmaceutical processes.
Our oil-free air compressor provides clean air supply, preventing oil contamination that could damage electronic components. It is suitable for applications such as pneumatic tools, electronic component blow-off, and cleaning in the electronics industry.
Our company has passed the German TUV class 0 oil-free certification, CE certification, ISO9001 certification and TS16949 certification. We are the first domestic enterprise to use water for internal cooling and lubrication in high-end screw compressors. We have taken the lead in launching a two-stage compression high-pressure micro-oil screw compressor with a pressure of 4.0MPa. Furthermore, we have developed the world's first 4.0MPa pressure oil-free screw compressor and the world's first 1.25MPa pressure oil-free vortex compressor.
