Oil-free Water Lubricated Air Compressor

The Oil-free Water Lubricated Screw Air Compressor represents a remarkable innovation in air compression technology. Distinguished by its water - lubricated system, it completely eradicates the necessity for oil during the compression process, guaranteeing a 100% oil - free and clean air output.
This compressor is equipped with a pair of precisely designed helical rotors. As they rotate, water is injected into the compression chamber, serving as both a lubricant and a coolant. This dual - function of water not only ensures smooth operation of the rotors but also effectively controls the temperature rise during compression, enhancing the overall efficiency of the compressor.
One of its most significant advantages is its suitability for applications with stringent air purity requirements. Industries such as food and beverage, pharmaceuticals, and electronics can rely on this compressor to provide contamination - free air, ensuring product quality and safety. Additionally, the water - lubricated system results in lower maintenance costs, as there is no need to replace oil filters or deal with oil - related issues. With its high - efficiency operation, low - noise performance, and environmental - friendliness, the Oil-free Water Lubricated Screw Air Compressor is an excellent choice for modern industrial needs.

LUOYOU Compressor (Shanghai) Co., Ltd., a professional manufacturer based in Shanghai with a foundation laid at the start of the 21st century, takes pride in presenting its cutting-edge Water-lubricated Screw Air Compressors, which stand as a testament to the company's core values of Stability, Energy Saving, and Innovation .

These compressors are equipped with the fifth-generation oil-free screw compressor technology, featuring air ends crafted from stainless steel alloy—a significant technological leap that transitions from the conventional copper air ends to more advanced stainless steel ones . The integrated design of these compressors eliminates the need for complicated pipelines and lines, thereby reducing the number of failure points and ensuring much more stable operation . When it comes to maintenance, they require fewer consumables such as air filter cores and water filter cores, making maintenance a straightforward task that doesn't demand professional operational skills, ultimately leading to lower maintenance costs .






  1. True Oil-free:By utilizing advanced sealing and isolation technology, the compressed air is cleaner and can attain a genuinely oil-free state.


  2. High Volumetric Efficiency: It is more energy-efficient than two-stage dry twin-screw air compressors by over 15% and more than 36% more efficient than one-stage dry twin-screw air compressors.


  3. Stable and Reliable:To avoid the frequent and costly maintenance issues associated with dry screw compressors, the host components operate smoothly under low load, ensuring a low noise level and extended durability.


  4. Low Maintenance Cost:Reducing the reliance on consumables such as lubricating oil, oil filters, and oil-gas separation cores, compared to traditional air compressors, significantly lowers maintenance costs. The annual maintenance expense is only one-fifth that of a conventional micro-oil air compressor.


  5. Environmentally Friendly:No waste oil is produced, and the discharged water does not require special treatment, thereby meeting environmental protection standards.
