What is an Oil-Free Air Compressor?

Oil-free air compressors help manufacturers create products with high air quality throughout the manufacturing process. This equipment typically has no mechanical contact inside the compression chamber, or it uses an alternate material like water or Teflon coating to protect the internal mechanisms without depending on oil lubrication. Oil-free air compressors can provide air purity, environmental benefits and significant cost savings for manufacturers.

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.
