Biogas blowers - multi-stage

Landfill and digesters

Extraction of biogas, wastegas or landfill-gas belong to the main applications of Continental blowers. Our multi-stage blowers are used for the  removal of biogas from the extraction zone of the biogas to the combustion system (Burner, thermal motor, etc.).

The Continental Industrie centrifugal blowers are also used for the landfill vacuum gas extraction of volatile organic compounds (VOC´s) through pumping wells.

Wide flow and pressure range

The durability of the centrifugal blowers, their specific "biogas type" sealing system and their performance characteristics are all well suited to these applications which require operation over a wide volumetric flow range.

Gas handling

Safety first

The handling of compressed gases must be considered more hazardous than the handling of liquids and solids. The procedures adopted for the safe handling of compressed gases are centred on containment of the material, to prevent its escape to the atmosphere, and proper control of pressure and flow.


Our machines can run continuously, even under extreme conditions, and are capable of handling a variety of gases without risk of contamination, operating efficently and reliably without leaks.


The main advantages of Continental Industrie centrifugal blowers and exhausters are the simple and robust design, both of great importance for gas handling applications.

Continental Industrie machines comply to the ATEX directive.
