Mature technology

AQ series compressor core-unique water injection twin screw rotor, efficient operation closer to isothermal compression.Ultra-high strength polymer composite rotor, optimized rotor profile and water-lubricated bearings ensure that the rotor is not contaminated by oil and produce pure oil-free compressed air.

Twin screw rotor

High-quality ultra-high strength polymer composite rotors with optimized profiles for efficient compression.Anti-corrosion and highly efficient raw materials and true water spray lubrication result in a longer service life.

Rotor housing

The VSD Oil-Free Water-Lubricated Air Compressor is made of aluminum bronze with a corrosion-resistant housing for strength and durability.

Bearing

There is no physical contact inside the hydrodynamic bearing, only sliding through the water film, no grease lubrication, to ensure a long service life.

Compression efficiency of water lubrication

Water has excellent cooling power and effectively removes heat from the source.Energy waste caused by heat generation is eliminated, and more compressed air can be produced per kilowatt of energy.The cooler compressed air reduces thermal stress on the components, thereby extending service life.

Excellent water lubricated rotor

·Increase exhaust volume

·Reduce unit energy consumption

·Near isothermal compression

·Pressure ratings of 7, 10 and 13 bar.

·The efficient cooling capacity of water, combined with precise design, ensures AQ's superior energy efficiency.

VSD: Cutting Energy Costs

Compressor energy consumption accounts for more than 70% of the entire life cycle cost, and the production of compressed air consumes more than 40% of the total electricity bill of the plant.To reduce energy consumption, Atlas Copco developed the VSD Oil-Free Water-Lubricated Air Compressor.VSD technology not only saves a lot of energy, but also protects the environment for future generations.Thanks to its continuous investment in this technology, Atlas Copco offers a wide range of variable speed drive (VSD) air compressors on the market.

VSD: Energy consumption fluctuates with gas demand

● 35% average energy saving in production processes with dramatic changes in gas demand

Elektronikon° color screen controller controls motor speed and inverter

● No idle and empty waste

● Special design VSD motor, can start/stop at full pressure, no unloading waste

● Eliminate peak starting current

● Low operating pressure reduces system leakage

● EMC electromagnetic compatibility in accordance with standards (2004/108/EG)

Constant speed: non-adjustable energy consumption

Traditional constant speed compressors have only one speed and are 100% open.This results in a significant waste of energy when demand is low.

Up to 35% energy savings

Atlas Copco's AQ VSD technology tracks customer gas usage changes and adjusts compressor speeds in real time, achieving average energy savings of up to 35 percent and total lifecycle cost savings of approximately 22 percent.

Total compressor life cycle cost

● Energy consumption cost

● Energy savings from VSD

● Equipment purchase cost

● Maintenance costs
