The oil-free screw compressor working principle is based on two intermeshing rotors, or screws, that compress air without the need for oil inside the compression chamber. Unlike lubricated compressors, which use oil to seal and cool the compression process, a dry oil free rotary screw air compressor relies on precision engineering, advanced coatings, and durable materials to minimize wear.

Learn how to evaluate & choose a two-stage rotary screw compressor for maximum energy savings, lower specific power, and efficient compressed air performance.
