Our CM160B Oil-free Screw Air Compressor adopts a truly oil-free design, using no lubrication in the main unit. It utilizes pure water to cleanse the compressed air of any acidic and alkaline substances, making it purer and safer for use.
All pipelines are made from corrosion-resistant materials such as 304 and 316 stainless steel. With the adoption of synchronous direct-drive technology between the motor and the main unit, the maximum rotation speed does not exceed 2980rpm/min, prolonging the lifespan of the bearing and rotor.
We employ direct water cooling for the rotor and cavity, ensuring higher isothermal compression efficiency. Furthermore, our double compression chamber technology, featuring one rotor and two compression chambers, surpasses two-stage compression, eliminating the need for intermediate cooling and reducing power consumption.
Regular maintenance only requires the replacement of air and water filters, significantly reducing maintenance costs and time.
Our oil-free screw air compressor uses a pair of primary screws, the pressure screw and the rotating screw, to complete the compression process. These screws, typically made from high-strength alloy steel, have precise helical shapes. When the screws rotate, the working chamber gradually expands, drawing external air in via the intake. Once the air enters, the rotation of the screws causes the chamber to gradually shrink, increasing the air's compression ratio and pressurizing it. This compressed air is then pushed to the machine's outlet.
The compression process produces heat, necessitating a cooling system to reduce the temperature. Additionally, to ensure air quality, the compressed air needs to be cleaned by a filtration system to remove potential contaminants and particles.
Our oil-free air compressor provides an oil-free air supply, eliminating the risk of oil contamination, making it suitable for pneumatic operations, packaging, and processing in the food and beverage industry.
Oil-free air compressors can provide oil-free, sterile air, making them suitable for surgical 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, making it suitable for pneumatic transport, packaging, and sterilization in the pharmaceutical process.
Our oil-free air compressor provides clean air, preventing oil contamination damage to electronic components, and is suitable for pneumatic tools, electronic component blow-off, and cleaning applications in the electronics industry.
Our company's entire product range has passed 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 screw compressors. We have also pioneered the global launch of a second-stage compression high-pressure micro oil screw compressor with a pressure of 4.0MPa, and subsequently developed the world's first 4.0MPa pressure oil-free screw compressor and the world's first 1.25MPa pressure oil-free vortex compressor.
