18KW AQ-18 VSD OIL-FREE WATER ATLAS COPCO INJECTED SCREW COMPRESSORS

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.

Water-injected screw element
• Highly energy-efficient thanks to low temperatures.
• Water-lubricated, grease-free bearings.
• In-house design and manufacturing.
• Working pressure up to 13 bar.

Water filter
• Ensuring a constant supply of clean water.
• The filtration capability equals 10 micron throughout the filter’s lifetime.

Heavy-duty air filter
• Protects the compressor components by removing 99.9% of dirt particles down to 3 microns.
• Differential inlet pressure for proactive maintenance while minimizing pressure drop.

Reverse osmosis system
•The built-in reverse osmosis system provides a reliable supply of high quality water, ensuring autonomy and continuous operation.

Air-cooled fan and water-cooler
• Air and water-cooled variants are available throughout the range.
• Small footprint and installation thanks to built-in heat exchangers.
• Water-cooled units provide a continuous air temperature at the dryer inlet of less than 55°C (131°F).

Integrated highly efficient dryer
• Excellence in air quality.
• 50% reduction in energy consumption compared to traditional dryers.
• Zero ozone depletion.

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.
