The revolutionary G-BH7 side channel blowers can create pressure differences of up to 1,000 mbar - more than any other gas ring compressor! So far, the systems used to reach these differential pressure ranges were much louder and larger - or subject to wear. Now the advantages of wear-free operation coupled with a low noise level can also be used in the most demanding applications. The G-BH7 vacuum pumps and compressors can work up to 20,000 hours without maintenance down time. These specialist machines have proven their reliability under the harshest of conditions. Their noise level was already impressively low, but our engineers and designers were able to make them even more quiet.

The use of a frequency converter mounted directly to the motor or installed separately in a switchgear cabinet can considerably increase compressor capacity without an increase in size. Speeds of up to 6000 rpm (100 Hz) can be achieved with standard machines. Needless to say, only those materials are used which comply with the requirements of the RoHS. Furthermore, these machines can be supplied without delay and are also available in ATEX certified form.
