CM22B(F) Oil-free Screw Air Compressor Of Water Lubrication

Advantages of our Oil-free Screw Air Compressor

1. True Oil-free Screw Air Compressor

   Our compressor employs zero lubrication oil, eliminating the need for jacket cooling oil, and uses pure water to cleanse acidic and alkaline substances from the compressed air, making it even purer.

2. Lifetime Stable and Reliable Oil-free Screw Air Compressor

   All pipelines are made of 304, 316 stainless steel or corrosion-resistant materials. With the adoption of direct-drive technology between the motor and the host, the maximum speed of the host does not exceed 2980rpm/min, ensuring a longer lifespan for the bearings and rotors.

3. More Energy-saving Oil-free Screw Air Compressor

   We employ direct rotor and cavity water cooling for higher isothermal compression efficiency and dual compression cavity technology, where one rotor serves two compression cavities, surpassing two-stage compression. This eliminates the need for intermediate cooling, reducing power consumption losses.

4. Lower Maintenance Cost Oil-free Screw Air Compressor

   Regular maintenance only requires the replacement of the air and water filters, reducing maintenance costs significantly.

Compression Principle of Our Oil-free Screw Air Compressor

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 of high-strength alloy steel, have a precise helical shape. The helical shape of the pressure screw and the rotating screw forms a sealed working chamber in between them during the intake process. As the screws rotate, the working chamber gradually enlarges, drawing in external air through the intake port. Once the air enters the working chamber, the rotation of the screws causes the working chamber to gradually reduce, which in turn increases the compression ratio of the air, thereby increasing its pressure. The compressed air is then pushed towards the outlet of the machine. The compressed air generates heat during the compression process, necessitating a cooling system to lower the temperature. Additionally, to ensure air quality, the compressed air needs to be cleaned through a filtration system to remove potential contaminants and particles.
