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.
Superior water-injected screw element
• Increased free air delivery.
• Low specific energy consumption.
• Near isothermal compression process.
• Pressure ratings of 7, 10 and 13 bar.
The highly effective cooling capabilities of water combined with precision engineering ensure the supreme energy efficiency of the AQ compressors.
Why Atlas Copco Variable Speed Drive technology?
• On average 35% energy savings during fluctuations in production demand with an extensive turndown range.
• Integrated Elektronikon Graphic controller controls the motor speed and high efficiency frequency inverter.
• No wasted idling times or blow-off losses in normal operation.
• Compressor can start/stop under full system pressure without the need to unload with special VSD motor.
• Eliminates peak current penalty during start-up.
• Minimizes system leakage due to a lower system pressure.
• EMC Compliance to directives (2004/108/EG).
