Atlas Copco’s rotary screw compressors

Made to last and will run 24/7 due to their energy efficient design.

Rotary air compressors are positive displacement compressors.

These compressors consist of two rotors within a casing where the rotors compress the air internally.

There are no valves.

These units are basically oil cooled (with air cooled or water cooled oil coolers) where the oil seals the internal clearances.

Since the cooling takes place right inside the compressor, the working parts never experience extreme operating temperatures.

The rotary compressor, therefore, is a continuous duty, air- cooled or water-cooled compressor package.

Rotary screw air compressors are easy to maintain and operate.

Advantages of the rotary screw compressor include smooth, pulse-free air output in a compact size with high output volume over a long life.

The oil-free rotary screw air compressor utilises specially designed air ends to compress air without oil in the compression chamber yielding true oil-free air.

Oil-free rotary screw air compressors are available air-cooled and water-cooled and provide the same flexibility as oil- flooded rotaries when oil-free air is required.
