Your advantages with AQUAAIR screw compressors

Only AQUAAIR offers this.

You need oil-free compressed air – powerful, reliable and cost-effective?

In demanding, industrial compressed air generation, screw technology has prevailed. A screw compressor with a high volume flow is powerful and reliable with high availability in continuous operation.

The economy of a screw compressor, particularly energy efficiency, is competitive to other compressed air generation technologies when a coolant and lubricant is used.

Oil-free compressed air can be produced economically with a screw compressor if water is used as a coolant and lubricant.

Water-injected screw compressors from AQUAAIR are powerful, highly efficient and extremely economical.

Maximum efficiency


About 80% of the compressed air costs are electricity costs. The economics of a screw compressor is therefore highly dependent on its energy efficiency.

Following the gas equation for a closed system (p0 x V0 / T0 = P1 x V1 / T1 = R = constant) an isothermal (T1 isotherm: = T0) compression of the ambient air is the physical optimum.

The energy efficiency of a screw compressor is thus better the lower the difference between the compression temperature (T1) and the ambient temperature (T0) drops out.

As the compression temperature of dry-running screw compressors increases to 240 degrees Celsius, oil or water is injected into the air end, primarily for cooling, but also for lubrication and sealing.

The compression temperature of an oil-injected air end rises to 100 degrees Celsius, with a water-injected air end from AQUAAIR only 10 degrees Celsius above ambient temperature.

Water-injected air ends from AQUAAIR compress atmospheric air almost isothermal with minimal current consumption and thus highly efficient.

Water-injected screw compressors from AQUAAIR are extremely economical thanks to the highly efficient AQUAAIR air end, the AQA_AIR Management and the innovative system concept, which consume significantly less power than conventional compressors, especially in the case of highly variable compressed air requirements. – The specifics of the AQUAAIR air end allows the integrated VFD air pressure control to take full effect with variable compressed air requirements.

Depending on the application, these systems can save up to 35% energy! – Only AQUAAIR offers this.

  • No waste by oil filtration

Oil lubricated screw compressors turbulate clean ambient air with oil so that the actual compression of air becomes more economical. – The subsequent oil filtration, however, again destroys a significant part of the energetic advantage. If the generated compressed air is to be almost free of oil, the oil filtration is expensive.

Water-lubricated screw compressors from AQUAAIR use the most natural and environmentally friendly lubricant available – water! – with excellent performance data.

The AQUAAIR screw compressors contribute significantly to the economic efficiency of your compressed air generation. The effort and cost for procurement, filtration and disposal of oil-containing lubricants are eliminated. – To your advantage, good for the environment.

  • No expensive water treatment

AQUAAIR gains the necessary lubricant – water – directly and exclusively from the ambient air. – An expensive water treatment is not necessary. – This has a measurably positive effect on the overall productivity.

  • Integrated VFD air pressure control with high energy efficiency in partial load operation

A VFD air pressure control generally adjusts the speed of a screw compressor to the current compressed air demand and reduces the absolute current power consumption in partial load operation.

However, in conventional compressors with VFD air pressure control, the relative energy efficiency in the partial load operation deteriorates significantly, i.e. the energy consumption per produced volume of compressed air increases significantly as a result of increasing flow losses.

In the case of AQUAAIR screw compressors, the already high energy efficiency continues to increase in the partial load operation; the energy consumption per compressed air produced continues to fall. – This means that AQUAAIR screw compressors with integrated VFD compressed air control are highly efficient and extremely economical, especially for variable compressed air requirements. – Only AQUAAIR offers this.
