Multistage centrifugal units are known for their reliable operation under tough conditions or in high-risk environments. That is why they are used in a variety of applications in the oil, biogas, or mining industries. They are suited for both pressure (multistage blowers) and vacuum (multistage exhausters) applications of air and gases.

The strength of the multistage blower design is the ability to select both the number of compression stages and the impeller design of each stage. This will help you to match the blower performance to your process requirements with maximum efficiency.

Multistage blowers are often used in the production process for biogas. They are used to extract gas from e.g. sludge so that it can be purified and turned into biogas. Gasses such as methane and carbon dioxide cause corrosion. For your biogas production process, you'll need a robust unit that can withstand corrosion.
