Our oil-free screw air compressor offers several unique advantages:
Our compressor contains no lubricating oil, eliminating the need for mainframe jacket cooling oil. Pure water is used to clean acidic and alkaline substances in the compressed air, making it purer.
All pipelines are made of 304, 316 stainless steel or corrosion-resistant materials. The motor and the mainframe are directly connected at equal speed, ensuring the maximum speed of the mainframe does not exceed 2980rpm/min. The lifespan of the bearings and rotors is thus extended.
Direct water spray cooling of the rotor and cavity provides higher isothermal compression efficiency. Our double compression chamber technology, which allows for two compression chambers for one rotor, surpasses two-stage compression and eliminates the need for intermediate cooling, reducing energy consumption.
Regular maintenance only requires the replacement of air filters and water filters, resulting in lower overall maintenance costs.
The 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 are typically made from high-strength alloy steel and have precise helical shapes. The helical shape of the pressure screw and rotating screw forms a sealed working chamber between them during the inhalation process. As the screws rotate, the working chamber gradually expands, allowing external air to enter the working chamber through the inhalation port. Once the air enters the working chamber, the rotation of the screws causes the working chamber to gradually shrink. This compression increases the pressure of the air. The compressed air is then pushed towards the machine's outlet. The air heats up during the compression process and requires a cooling system to lower the temperature. To ensure the quality of the air, the compressed air must also 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. 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, suitable for operating rooms, laboratories, and other pneumatic operations in hospitals.
Our oil-free air compressor can provide oil-free, sterile air that meets pharmaceutical standards. It is suitable for pneumatic conveying, packaging, and sterilization in the pharmaceutical process.
Our oil-free air compressor provides a clean air supply, avoiding oil contamination that can damage electronic components. It is suitable for pneumatic tools, electronic component blowing and cleaning applications in the electronics industry.
air compressor application">We are the first domestic enterprise to use water for internal cooling and lubrication of high-end screw compressors. All our products have passed Germany's TUV Class 0 Oil-Free Certification, CE Certification, ISO9001 Certification, and TS16949 Certification. We were the first in the world to introduce a two-stage compression high-pressure micro-oil screw compressor with a pressure of 4.0MPa. 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.
