Our CM110B oil-free screw air compressor is completely devoid of any lubricating oil. It utilizes pure water to cleanse the compressed air of acidic and alkaline substances, resulting in cleaner, purer air. This feature ensures a healthier and more environmentally friendly operation.
All pipelines of our compressor are made from 304, 316 stainless steel or corrosion-resistant materials. The motor and the main unit are directly connected at the same speed, ensuring a maximum rotation speed of no more than 2980rpm/min. This enhances the life expectancy of the bearings and rotor, making our compressor more durable and reliable.
Our CM110B oil-free screw air compressor uses direct water spray to cool the rotor and cavity, leading to a higher isothermal compression efficiency. It employs dual compression chamber technology, with one rotor and two compression chambers, surpassing two-stage compression and reducing power consumption loss.
Regular maintenance of our compressor only requires the replacement of air and water filters, reducing the cost and time involved in maintenance.

Our oil-free screw air compressor uses a pair of primary screws, the air pressure screw and the rotating screw, to accomplish the compression process. These screws are usually made of high-strength alloy steel with precise helical shapes.

During the intake process, their helical shape forms a sealed working chamber between them. As the screws rotate, the working chamber gradually expands, allowing external air to enter via the intake port. Once the air is in the working chamber, the rotation of the screws causes the working chamber to gradually shrink. This shrinking gradually increases the compression ratio of the air, thereby increasing its pressure. The compressed air is then pushed towards the machine's outlet. The compression process generates heat, which is managed by a cooling system. To maintain air quality, the compressed air also needs to be cleaned by a filtration system to remove any potential contaminants and particles.
Our 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 operating rooms, laboratories, and other medical equipment pneumatic operations in hospitals.
Our oil-free air compressor can provide oil-free, sterile air that meets pharmaceutical standards, suitable for pneumatic transport, packaging, and sterilization in pharmaceutical processes.
Our oil-free air compressor provides a clean air supply, avoiding oil contamination damage to electronic components. It is suitable for pneumatic tools, electronic component blowouts, and cleaning applications in the electronics industry.


Our company's full range of products has passed Germany's TUV class 0 oil-free certification, CE certification, ISO9001 certification, TS16949 certification. We are the first domestic company to use water for internal cooling and lubrication of high-end screw compressors, and the first worldwide to launch a two-stage high-pressure micro oil screw compressor with a pressure of up to 4.0MPa. We also developed the world's first 4.0MPa pressure oil-free screw air compressor and the world's first 1.25MPa pressure oil-free vortex compressor.
