G-Series Side Channel Blowers in Pressure Operation
Compressors G-BH1 00
Volume flow
21 to 35 m³/hr
12.4 to 20.6 cfm
The smallest side channel blower on the market. 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.
Side Channel Compressors
Vacuum pumps G-BH1
Volume flow
50 to 2450 m³/hr
29.4 to 1441.2 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.
Compressors G-BH2
Volume flow
330 to 850 m³/hr
194.1 to 500.0 cfm
Series G-BH2 machines are equipped as standard with highly efficient drive motors
(efficiency class 1 - eff1), which also feature multi-frequency and wide voltage range coils permitting use
throughout the world on wide ranging mains power supplies and the operation of frequency converters up
to 100 Hz (6000 rpm).
By using the VELOCIS, you will protect the environment and save money.Needless to say, only those
materials are used which comply with the requirements of the RoHS.
Compressors G-BH7
Volume flow
50 to 230 m³/hr
29.4 to 135.3 cfm
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.
Compressors G-BH8
Volume flow up to 950 m3/hr, 560 cfm
Differential pressure up to 720 mbar
Compact design
The G-BH is about half as large (installed volume) and nearly 60% lighter than a comparable standard
machine with the same performance characteristics.
Quiet
Modern sound engineering: only half as loud (78 db(A) versus 84 db(A))
Economical
Cuts costs for: shipping (low weight), packaging (smaller), electrical installation (smaller cross sections
and smaller circuit protection devices), electrical energy (high efficiency and good controllability).
Energy-saving operation with Variable speed drive.
Flexible
These units are normally operated with frequency converters. The housing components can be rotated in
45° increments without manifolds and silencers or in 90° increments with manifolds and silencers.
Together, both of these features offer maximum flexibility upon integration in the overall system.
Regarding IE3
200 Hz motors which are used in this side channel blower do not fall under IE regulations.
UL/CSA approval for worldwide use
20,000 operating hours. Pulsation-free. Virtually maintenance-free.
