High efficiency

The superior cooling capability of water ensures that heat is removed efficiently at the source to generate more 

air per kW of power 

Energy savings

Variable Speed Drive versions offer energy savings of up to 35% by eliminating load/no load transition losses. 

Precise pressure control allows a tighter pressure band and a lower average working pressure for reduced energy 

consumption

Certified 100% oil-free air

AQ compressors provide 100% pure, clean air that meets the ISO 8573-1 CLASS 0 (2010) standard. CLASS 0 means 

zero risk of contamination; zero risk of damaged or unsafe products; zero risk of losses from operational downtime; and
