Side Channel Blowers

G Series – Side Channel Blowers

Some technologies are so good that it is hard to improve them. Side channel blowers from Elmo Rietschle are such an example. They have proven their reliability in service for many decades, performing flawlessly day in and day out with virtually no down time.

Noise levels have been lower than that of most other vacuum pumps and compressors. Our side channel blowers are available in a wide selection for performance ranges up to 3,000 m³/h and differential pressures of up to 1,000 mbar. They cover the most varied requirements flexibly and powerfully.
