Our CM11B(F) compressor is a truly oil-free screw air compressor. Its main unit does not use any lubricating oil and does not require main body jacket cooling oil. Instead, it uses pure water to clean acidic and alkaline substances in compressed air, making it purer.
With all pipelines made of durable 304, 316 stainless steel or corrosion-resistant materials, our oil-free screw air compressor guarantees long-term stability and reliability. The motor and main unit are connected with equal speed technology, ensuring that the maximum speed of the main unit does not exceed 2980rpm/min. This enhances the lifespan of the bearing and rotor.
Our oil-free screw air compressor efficiently cools the rotor and cavity by directly spraying water, achieving higher isothermal compression efficiency. With the use of dual compression cavity technology comprising one rotor and two compression cavities, it surpasses two-stage compression and reduces power consumption loss by eliminating the need for intermediate cooling.
Our oil-free screw air compressor requires minimal daily maintenance. Replacing the air filter and water filter is all that is needed to keep it running smoothly.
Our oil-free screw air compressor uses a pair of main screws, namely, the pressure screw and rotating screw, to complete the compression process. These screws, usually made of high-strength alloy steel, have a precise spiral shape. As the screws rotate, the working chamber gradually expands, allowing external air to enter the working chamber through the intake port. As the working chamber shrinks due to the rotation of the screws, the compression ratio of the air gradually increases, thereby increasing the pressure of the air. The compressed air is then pushed towards the outlet of the machine. The entire compression process generates heat, necessitating a cooling system to reduce the temperature. Moreover, 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. 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, making it suitable for surgical rooms, laboratories, and other medical equipment in hospitals.
Our oil-free air compressor can provide oil-free, sterile air that meets pharmaceutical standards, making it ideal for pneumatic transportation, packaging, and sterilization in the pharmaceutical process.
Our oil-free air compressor provides clean air supply, preventing damage to electronic components due to oil contamination. It is suitable for pneumatic tools, electronic component blowing and cleaning, and other applications in the electronics industry.
We are the first domestic company to use water for internal cooling and lubrication in the high-end screw compressor manufacturing industry. Our full range of products has passed German TUV Class 0 oil-free certification, CE certification, ISO9001 certification, and TS16949 certification. We continue to innovate, and we were the first to introduce the second-stage compression high-pressure micro oil screw compressor with a pressure of 4.0MPa globally. We also developed the world's first 4.0MPa pressure oil-free screw compressor and the world's first 1.25MPa pressure oil-free vortex compressor.
