Oil Free Screw Compressor Catalogue

Screw compressors operate on the principle of positive displacement. Each screw compressor consists of a male and female screw. As no oil is injected during compression, the screw rotors may not touch each other, which is achieved by gears. As there is no cooling provided by the injected oil, oil free screw compressors are equipped with two compression stages. Special attentation is required for cooling downstream each compression stage.
