side channel blowers from Elmo Rietschle


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. 

Side channel blowers are used for conveying gases and gas-air mixtures.

The 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.

The G-Series side channel blowers feature voltage range motors for 50 and 60 Hz in protection class IP 55 (insulation class F) and are UL 1450 and CAN/CSA C22.2 No. 68-09 approved. This makes them the ideal solution for worldwide use: They can be used without modifications or tests in Europe, Asia and America.
