Air Blowers for Sewage and Wastewater Treatment

Oil-free air blower solutions for each Sewage and wastewater treatment application both industrial and municipal. We offer clean air technology that matches all your aeration needs. With high energy efficiency and low total cost of ownership.

Contact our expert

Our sales and service network is spread over 180 countries worldwide and we are servicing thousands of low pressure compressed air installations throughout the world, making sure your equipment is always working at peak efficiency and downtime is limited to a minimum.

Energy efficient blowers

For each application in a sewage or wastewater treatment plant we can provide you the most optimal solution. Our oil-free screw technology with variable speed drive for example, lowers your energy consumption by 30% on average compared to other technologies. Lowering your total cost of ownership.

Clean air for treating wastewater

All our blowers are ISO 8573-1 (2010) Class 0 certified: Guaranteeing that the air is not contaminated during the compression process. We are the only compressor and blower manufacturer that has ISO 22000 certifications.

All blower technologies available

We offer all blower and low-pressure technologies, developed and produced in house by our engineers. Ideal for sewage and wastewater treatment applications. Lower noise and vibration levels or airflow regulation with a variable speed drive. Our products can be tailored to match all your needs.

Why work with us?

Help you reduce your ownership cost

Up to 70% of the energy consumption in a sewage or wastewater treatment plant is used by air blowers. So, keeping energy costs down is key to keeping total operational costs low. To ensure we keep your operational costs down, we designed the most efficient and reliable machines on the market. This will ensure a faster return on investment!

Help you reduce environmental impact

Efficient water management becomes increasingly important due to scarce availability of resources and the rising financial pressure. When counting on an air supply to keep the bacteria alive during the treatment process oil contamination is not desirable. That is why our products are oil-free, helping you, in addition to reducing your energy consumption, to further reduce your impact on the environment.

We offer a global installation base

Our sales and service network is spread over 180 countries worldwide and we are servicing thousands of low pressure compressed air installations throughout the world, making sure your equipment is always working at peak efficiency and downtime is limited to a minimum.

We offer low budget mini skid packages

We can supply low budget mini skid packages to water supply companies. This screw compressor with desiccant dryer solution is perfect both for clean water and wastewater treatment plants. It provides dry air used for instrumentation and, with condensate filtration on the skid, is compliant with environmental regulations. Available with a sharp lead time and extra cost of only £4000 on top of the equipment.

Customer stories


Diffused aeration

As bacteria can't survive without oxygen, a continuous oil-free air supply is important for the quality of your wastewater treatment process. The supply of wastewater can vary during the day so it's crucial that your blower installation can handle a variable air flow demand. We offer you both fixed speed blowers with a high turndown as well as energy efficient variable speed drive blowers.

Filter backwashing

Backwashing refers to pumping water backwards through the filter. Oil-free air prevents filter media from becoming dirty and unusable. It is a form of preventive maintenance so that the filter media can be reused.

Aerated lagoon

An aerated lagoon is a treatment pond that promotes biological oxidation of wastewaters. The diffused aeration system's efficiency has a direct impact on the quality and level of wastewater treatment that the lagoon achieves.

Activated sludge process

Air and microorganisms are used to biologically oxidize organic pollutants, producing waste sludge containing oxidized materials. The air in conventional activated sludge systems must be oil free to avoid contamination of the water.

Sequencing Batch Reactor (SBR)

SBRs are activated sludge processes designed to operate under non-steady state conditions. Operated in true batch mode with aeration and sludge settlement in the same basin. During the aeration phase, airflow is diffused in the tank. Thanks to fixed speed units the energy consumption is much lower, generating a competitive cost advantage.

Membrane bio-reactor (MBR) systems

A version of the conventional activated sludge system where solid and liquid separation is done by a membrane (micro- or ultrafiltration). Resulting in advantages for process control and product water quality but high energy consumption and intensive bio treatment process.
