Oil Free Screw Air Compressor: The Ultimate Solution For Pure Power

In the industrial field that pursues high-quality compressed air, oil-free screw air compressors have gradually become the preferred solution. Compared with traditional oil compressors, oil-free screw air compressors are designed to avoid contact between lubricating oil and compressed air, thereby ensuring the purity of the output air. This characteristic is particularly important for industries that have strict requirements for air quality, such as healthcare, food processing, electronic manufacturing, and laboratory research.

The oil-free screw air compressor adopts a specially designed host, which can compress without the need for oil injection, so there will be no oil mist or droplets mixed into the compressed air, eliminating the risk of oil pollution. Whether it is air-cooled or water-cooled models, these compressors provide the same flexibility and reliability as oil screw compressors, while meeting the high standard demand for clean air.

Single Screw Compression Technology

The compression unit in this design features a screw and two star wheels, resulting in a total of 12 compression chambers. Each full rotation delivers twelve compressions, which significantly enhances efficiency. Single screw compression structures offer optimal stress conditions, allowing the screw to withstand higher pressures and extend its operational life.

1. Advanced Oil-Free Technology for Lifelong Clean Air

This system employs stainless steel components and uses water as the lubricating medium to achieve fluid dynamic lubrication, maintaining a controlled gap. With a main engine speed of just 3000 RPM, there’s no need for lubricating oil in the bearings, eliminating any risk of oil contamination. Designed to last over 100,000 hours, the CM series guarantees the delivery of clean, oil-free compressed air for life. This is possible thanks to the unit’s use of water as a lubricant, along with the absence of a gearbox, cooling oil, and mechanical seals.

2. Ultra-Low Exhaust and Operating Temperatures

By injecting water directly into the main unit for both lubrication and cooling, the unit’s operating temperature stays below 45°C, avoiding the risks of burns or fire hazards. Furthermore, the lower exhaust temperature minimizes the moisture content in the compressed air, reducing the load on post-treatment equipment and improving its overall efficiency.
