Our oil-free screw air compressor is designed with no trace of lubricating oil in the host. It doesn't need host jacket cooling oil and adopts pure water to clean acidic and alkaline substances in the compressed air, making it more pure.
All pipelines of our oil-free screw air compressor are made of 304, 316 stainless steel or corrosion-resistant materials. With the adoption of motor and host isochronous direct connection technology, the maximum speed of the main machine does not exceed 2980rpm/min, which ensures a longer lifespan for the bearings and rotors.
We cool the rotors and chamber directly with water, which makes the isothermal compression efficiency higher. The use of double compression chamber technology, a rotor with two compression chambers, surpasses two-stage compression, eliminating the need for intermediate cooling and reducing power consumption loss.
The daily maintenance of our oil-free screw air compressor only requires the replacement of air and water filters, which helps in reducing the maintenance cost.
The oil-free screw air compressor uses a pair of main screws, i.e., the pressure screw and the rotating screw, to complete the compression process. These two screws are usually made of high-strength alloy steel and have precise spiral shapes.
During the intake process, the spiral shape of the pressure screw and rotating screw forms a sealed working chamber between them. As the screws rotate, the working chamber gradually expands, causing external air to enter the working chamber through the intake port. Once the air enters the working chamber, the rotation of the screws causes the working chamber to gradually shrink. This shrinkage gradually increases the compression ratio of the air, thereby increasing the pressure of the air.
In this process, the air is compressed and pushed towards the machine's outlet. The compressed air generates heat during the compression process, and hence a cooling system is needed to reduce the temperature. Also, to ensure the air quality, the compressed air needs to be cleaned through a filtration system to remove potential pollutants and particles.
Our oil-free air compressor provides an oil-free air supply, avoiding the risk of oil contamination, and is suitable for pneumatic operations, packaging, and handling in the food and beverage industry.
Oil-free air compressors can provide oil-free, sterile air, suitable for pneumatic operations in hospital operating rooms, laboratories, and other medical equipment.
Oil-free air compressors can provide oil-free, sterile air that meets pharmaceutical standards, suitable for pneumatic conveying, packaging, and sterilization in the pharmaceutical process.
Our oil-free air compressor provides a clean air supply, avoiding oil contamination damage to electronic components, and is suitable for applications such as pneumatic tools, electronic component blowing and cleaning in the electronics industry.
Our company's full range of products has passed 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 the compressor, and the first to launch a second-stage compression high-pressure micro-oil screw compressor with a pressure of 4.0MPa globally. We then developed the world's first 4.0MPa pressure oil-free screw compressor and the world's first 1.25MPa pressure oil-free vortex compressor.
