POWERFUL OIL-FREE AIR

When it comes to clean, oil-free compressed air, you cannot afford to compromise on quality.

Over the past decades, Atlas Copco has pioneered oil-free water-injected screw technology, resulting in a broad range of compressors delivering 100% oil-free, clean air. Setting the standard through ISO 8573-1 CLASS 0 certification, the AQ meets your need for pure oil-free air while offering best in class energy efficiency.

PROVEN TECHNOLOGY

At the heart of the new AQ range is a unique water-injected screw element working highly efficient near isothermal compression. The polymer ceramic rotors with their optimized rotor profile are supported by water-lubricated bearings, ensuring that no oil whatsoever can contaminate the compression element, thereby producing pure oil-free air.

Rotors

A highly efficient compression process is achieved thanks to high quality polymer mould ceramic rotors with optimum profiling. The combination of corrosion-free, high efficiency raw material and water lubrication results in a longer lifespan.

Element housing

Strength and durability are ensured as a result of the aluminium bronze element housing without risk of corrosion within the element.

Element bearings

The use of hydrodynamic bearings ensure long life as no physical contact is made within the bearing itself, it simply glides on a film of water removing the need for any oil or grease lubrication.
