Our oil-free screw air compressor offers a multitude of benefits that make it a highly efficient and reliable choice.
Our compressor is a true oil-free screw air compressor as the host does not contain a drop of lubricating oil. It does not require host jacket cooling oil and uses pure water 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 material. The adoption of isomeric speed direct connection technology between the motor and the host ensures that the maximum rotation speed of the host does not exceed 2980rpm/min, thereby extending the lifespan of the bearing and rotor.
Our oil-free screw air compressor employs direct water spray cooling of the rotor and cavity for higher isothermal compression efficiency. The double compression cavity technology, where one rotor has two compression cavities, 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 the air filter and water filter, resulting in lower maintenance costs.
The oil-free screw air compressor uses a pair of primary screws, the pressure screw and rotating screw, to complete the compression process. These screws are typically made of high-strength alloy steel and have precise helical shapes. The helical shape of the pressure screw and rotating screw creates a sealed working chamber between them during the intake process. As the screws rotate, the working chamber gradually expands, allowing 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. During this process, the air is compressed and pushed towards the machine's outlet. The compressed air generates heat during the compression process, requiring a cooling system to lower the temperature. To ensure the quality of the air, the compressed air also needs to pass through a filtration system to remove potential contaminants and particles.
The oil-free air compressor provides an oil-free air supply, avoiding the risk of oil contamination, making it suitable for pneumatic operations, packaging, and processing in the food and beverage industry.
The oil-free air compressor can provide oil-free, sterile air, suitable for operating rooms, laboratories, and other pneumatic operations of medical equipment in hospitals.
The oil-free air compressor can provide oil-free, sterile air that meets pharmaceutical standards, suitable for pneumatic transport, packaging, and sterilization in the pharmaceutical process.
The oil-free air compressor provides clean air supply, avoiding oil contamination damage to electronic components, suitable for pneumatic tools, electronic component blowing and cleaning applications in the electronics industry.
Our company is the first domestic enterprise to use water for internal cooling and lubrication of high-end screw compressors, and we were the first to launch a second-stage compression high-pressure micro-oil screw compressor with a pressure of up to 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. All our products have passed German TUV class 0 oil-free certification, CE certification, ISO9001 certification, and TS16949 certification.
