With a wide range of variants.
Designed for harsh applications, ensures mechanical integrity during process malfunctions
Lowest power consumption at vacuum
With rotational speeds from 540 to 3960 rpm
Reduced installation costs and minimal in situ service to maximise process uptime
Innovative modular rotor technology ensures high performance on the smallest footprint and weight. This ensures the highest degree of flexibility when designing large vacuum systems.
The GMB40K is scalable with multiple backing configurations available. Built to global standards IEC and NEMA flange compatibility. ATEX options are also available for use Hazardous or chemical applications.
