Product Details

7.5~75kW PM Variable Speed Oil free Screw Air Compressor

Product feature

Optimal Water Lubricated Screw Unit

The oil-free water lubricated screw unit adopts PEEK ultra-high-strength ultra-wear-resistant molecular material and aerospace-grade all-stainless steel rotor. The system piping and housing are also made of stainless steel.

Class 0 Oil-free

Water is used for lubrication, cooling, sealing and noise reduction. 100% oil-free and pollution-free, the used water is environmentally friendly and can be drained directly.

Reliable Solenoid Valve

Danfoss and ODE solenoid valves are selected, high sensitivity & longer lifetime.

Less Consumables and Easy Operation

Air filter and water filter only. Lubricating water is automatically replenished and drained regularly.
