The AQ rotary screw compressor delivers 100% oil-free clean air. Atlas Copco was the first manufacturer to receive ISO 8573-1 Class 0 (2001) certification for compressed air quality.

AQ compressors are water-injected systems, available in water-cooled and air-cooled versions. They offer a high-pressure capability and improved energy efficiency, reducing electricity bills by up to 40%.

As well as guaranteeing oil-free air, preventing oil from entering the compression process also ensures lower operating and maintenance costs.
