Volume flow
21 to 35 m³/hr
12.4 to 20.6 cfm

With a height and width of approx. 125 mm and a depth of approx. 60 mm, the G-BH1 00 blowers have the size of a CD and are the smallest gas ring vacuum compressors available on the market. Furthermore, the adjustable volume flow of the machines ensures that only the exact performance required is actually being supplied - not more.

These blowers are employed primarily in fine mechanical and medical technology applications. With their robust and built-to-last design, they are also used in other industries such as mechanical engineering.

The G-BH1 00 is driven via an electronically commuted DC motor. This guarantees a high level of efficiency and maintenance-free operation for more than 20,000 operating hours. The operating electronics are a standard feature of the machines which allow infinitely variable control of speed and output of the blower.

29.4 to 1,441.2 cfm

With their high inlet volume flow (up to 2,450 m³/h) and a differential pressure of up to -480 mbar), our low noise G-BH1 all-rounder have earned their reputation and convinced thousands of customers all over the world. They are reliable, low-maintenance and durable and are the first choice for many applications in mechanical engineering.

When used with a frequency converter the performance of the G-BH1 pumps and compressors can be increased considerably. The G-BH1 machines are UL/CSA approved and can be used without further testing all over the world. Motors comply with DIN EN 60034 and have IP 55 protection. Available at short notice or ex stock and also as ATEX certified models, it is a classic that has proven its innovative quality. Needless to say, only those materials are used which comply with the requirements of the RoHS.

Our 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.
