Save 30% on energy

Our oil-free screw blowers lower your electrical power consumption by an average of 30% compared to lobe technology.

Clean air

All our blowers are ISO 8573-1 (2010) Class 0- certified: 100% clean oil-free air for your wastewater treatment process .

Low noise levels

Compressed air solutions with low noise levels. Rain canopy available for outdoor use. No need for additional investment in extra buildings or sound reducing facilities.

Setting a new energy-efficient standard

In wastewater treatment plants, blower systems consume up to 70% of the total energy. We can help reduce your energy costs. As the first manufacturer to introduce the oil-free screw technology in wastewater treatment, we are committed to lower you energy usage significantly.

Reducing the carbon footprint of wastewater treatment

The demand for water increases while resources are reduced: efficient water management becomes increasingly important. Our blowers are completely free of oil, which is of critical importance. Contamination is just not acceptable when re-using water for other applications or keeping bacteria and microorganisms in sludge processes alive.

Global installed base and aftermarket service

We service thousands of low pressure compressed air installations throughout the world. Backed by a global and highly efficient logistics organization we ensure your equipment is always working at peak efficiency.

Diffused aeration

Clean air directly impacts the quality of your wastewater treatment process. A continuous air supply is equally important, as bacteria can only survive a few hours without oxygen.

Filter backwashing

Oil-free air prevents filter media from becoming dirty and unusable. Deal with multiple start and stop periods and avoid breakdowns thanks to the high volume capacity and sturdiness of our equipment.

Activated sludge process

This 24/7 process requires a lot of energy since it’s active 365 days a year. Oil-free screw technology helps you save on average 30% on energy to conventional lobe technology.

Sequencing Batch Reactor (SBR)

The airflow supplied by blowers is diffused in the tank. Our blowers are designed to minimize operation and maintenance costs, in line with our energy-saving compressed air equipment.

MBR systems

Requiring both a lot of energy and additional air supply to scour the membranes frequently, MBR system applications can be covered by our high volume air blowers.
