THE OIL-FREE SCREW COMPRESSOR

100% oil-free compressed air. The basic principle of the oil free compressor is similar to the oil-injected compressor, except no oil is injected during compression.

No oil means that there is no oil for sealing the rotors and for cooling the compressed air, elements and rotors. The rotors don’t touch each other, and the air gap between the two is very small, which translates into optimal performance.

These oil free compressors are ideal if your application requires 100% oil-free air.
