Oil Free Screw Compressor Packages

Bespoke designed, complete packaged systems

Our range of oil free screw compressors are supplied as bespoke designed, complete packaged systems for process critical applications throughout the world.

​There are many situations where oil free technology presents the best approach. Oil free screw compressors are available in different configurations and materials providing the most compact arrangement, to allow the handling of gases with high levels of liquid, dirt and particulates.

There configurations are eminently suitable for use with hazardous or corrosive gases, or where contamination is an issue.
