What is a single-stage centrifugal air compressor?

Centrifugal air compressors use centrifugal forces to create flow and pressure. Centrifugal technology is an extremely efficient way to generate compressed air.

The gearbox with the main drive shaft is driven by a motor. Both gearbox and main drive shafts drive the high-speed shafts with one or more impellers. Single-stage turbo compressors only have one impeller and deliver air at a pressure up to 2 bar(g).

What is the difference between a single and two-stage compressor?

The word “stage” refers to the number of compression stages the air goes through in order to reach the required air pressure. The high-speed turning impellers create the dynamic pressure build-up in the compressor. The number of impellers and thus stages will depend on the outlet pressure that is needed.

For applications that require 2 bar(g) or less, one impeller or a single-stage compressor is sufficient to meet the pressure demand. With a two-stage or (three-stage) compressor, higher pressures can be reached.

What makes our single stage turbo oil-free air compressors unique?

With the design of our ZHL, we want to offer a more energy-efficient solution for those applications that require a flow of 7000 m3/h or more and a pressure up to 2 bar(g)/ 29 psig. The innovative design ensures efficient air delivery, even when the process has a variable air demand.

On top of that,  our units are Class 0 certified. This ensures your process of oil-free, quality air.

Quality air

The unique double seal design ensures your production process of quality air. Thanks to the oil and air seals, no lubrication oil can’t enter the impellers, resulting in oil-free, Class 0 certified air delivery. 

A sustainable production process

Up to 80% of the total life cycle costs go towards its energy usage. Designing our compressors to be as energy-efficient as possible thus not only benefits the planet but also translates into a return on investment for you.
