Benefits
Exceptionally quiet operation
Advanced acoustic engineering gives G-BH2 a very low noise level, including at higher pressures. It is suitable for noise-sensitive environments.
Completely wear-free
No oil, no friction and no internal contact between components mean stable operation, consistent performance and minimal operating costs throughout the service life.
Smooth, pulsation-free operation
Side-channel technology provides a very even airflow without pulsations, which is essential for sensitive processes and stable industrial applications.
Speed control available
G-BH2 is suitable for frequency-converter operation up to 87 Hz, enabling flow and pressure to be adapted to actual process requirements while providing additional energy savings.
Suitable for global use
Motors with a 50/60 Hz voltage range, IP55 protection and UL/CSA/IEC/EN certifications enable worldwide use without additional adaptations.
