AQ oil-free screw compressors are based on a unique, highly efficient water-injected screw element that operates under near-isothermal compression conditions. Polymer ceramic rotors with an optimized rotor profile are supported by water-lubricated bearings. This means oil cannot contaminate the compression element in any way and pure, oil-free air is provided. Atlas Copco has been leading the industry in oil-free compressed air technology for over sixty years, benefiting from vast experience and constant technological innovation. Rigorous certification and testing procedures are carried out to ensure the air complies with the highest quality control standards. ISO 8573-1 CLASS 0 (2010) AQ water injection screw compressors with certification %100 oil free air produces.
