Side Channel Blowers in Pressure Operation ELMO G-Series

Compressors G-BH8

Volume flow
up to 950 m³/h
up to 558,8 cfm

The G-BH8: Half as large – twice as strong

Volumetric flow up to 950 m³/h
Differential pressure +720 mbar
Small design volume
Low weight
Energy-saving operation
Variable electronic speed control
Intrinsic safety built in 
Technical features:

Energy-saving operation through higher efficiency
Variable output control
Noise reduced by half
Pulsation-free compression
Virtually maintenance-free

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.

Modern sound engineering: only half as loud (78 db(A) versus 84 db(A))

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)

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.


Compressors G-BH1

Volume flow
50 to 2,450 m³/h
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 700 mbar, our low noise G-BH1 allrounders 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-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.


Compressors G-BH2

Volume flow
330 to 850 m³/hr
194.1 to 500 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.
