G-BH8 VACUUM PUMPS
Technical Features
- Volume flow up to 950 m3/hr
- Differential pressure up to 680 mbar
- Compact design
- Low weight
- Energy-saving operation
- Variable speed drive
- 20,000 operating hours
- Energy-saving operation through higher efficiency
- Noise level reduced by half
- Pulsation-free
- Virtually maintenance-free
- UL/CSA approval for worldwide use
- 50/60 Hz voltage range motors
- IE3 motors
Advantages
- 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) - 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.
G-BH100 VACUUM PUMPS
Technical Features
- Volume flow 21 to 35 m³/hr
- Volume flow 12.4 to 20.6 cfm
- Differential pressure up to 100 mbar
Advantages
- Height and width of approx. 125 mm and a depth of approx. 60 mm.
- Smallest side channel blower available on the market.
- Adjustable volume flow of the machines.
- Robust and built-to-last design.
- High level of efficiency.
- Driven via an electronically commuted DC motor.
- IE regulations do not apply to DC motors.
- 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.
