Our oil-free screw air compressor is truly oil-free. The compressor does not contain any lubricating oil, eliminating the need for cooling oil for the main jacket. It uses pure water to clean the acidic and alkaline substances in the compressed air, making it even purer.
All pipelines are made of stainless steel or corrosion-resistant materials, ensuring the longevity of the compressor. With the use of equal-speed direct connection technology between the motor and the main unit, the maximum speed of the main unit does not exceed 2980rpm/min. This results in a longer lifespan for the bearings and rotors.
Our compressor utilizes direct water spray cooling for the rotor and cavity, resulting in higher isothermal compression efficiency. With the use of dual compression chamber technology, one rotor has two compression chambers, surpassing two-stage compression and eliminating the need for intermediate cooling, reducing power consumption loss.
Regular maintenance only involves the replacement of the air filter and water filter, significantly lowering maintenance costs.
The oil-free screw air compressor uses a pair of primary screws, the gas pressure screw and the rotating screw, to complete the compression process. These screws are typically made of high-strength alloy steel and have a precise spiral shape. During the intake process, the spiral shape of the gas pressure screw and the rotating screw forms a sealed working chamber between them. As the screws rotate, the working chamber gradually expands, causing external air to enter the chamber through the intake. Once the air enters the chamber, the rotation of the screws causes the working chamber to gradually decrease, increasing the compression ratio and thus the pressure of the air. During this process, the air is compressed and pushed towards the outlet of the machine. The compressed air produces 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.
The oil-free 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.
The oil-free compressor can provide oil-free and sterile air suitable for pneumatic operations in hospital operating rooms, laboratories, and other medical equipment.
The oil-free compressor can provide oil-free and sterile air that meets pharmaceutical standards, suitable for pneumatic transport, packaging, and sterilization in the pharmaceutical process.
The oil-free compressor provides clean air supply, avoiding oil contamination damage to electronic components, suitable for applications like pneumatic tools, electronic component blowing and cleaning in the electronics industry.
Our company's full range of products has passed German TUV class 0 oil-free certification, CE certification, ISO9001 certification, TS16949 certification. We are the first company in the country to use water for internal cooling and lubrication of high-end screw compressors. We were the first to launch a two-stage compression high-pressure micro oil screw compressor worldwide, with pressure reaching 4.0MPa. We have 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.
