Built for 24/7 operationExtremely low maintenanceLight-weightCertified by UL/CSA/IEC/EN50/60 Hz voltage range motorsSpeed Adjusted via external or integral converterNoise levels are lower than other vacuum pumps and compressors
Popular models include BH100 – the smallest blower on the market, BH1 – a classic with innovative technology, BH2 Velocis - expanded performance ranges, BH7 – highest differential pressure available, and the BH8 – Half the size and twice the power. How Elmo Rietschle G-Series Works: The impellers in the G-Series machines are mounted directly on the motor shaft for contact-free compression. Maximum operational reliability, even at high differential pressures, is ensured by the arrangement of the bearings outside the compression chamber. The gas is taken in through the inlet. As it enters the side channel, the rotating impeller imparts velocity to the gas in the direction of rotation. Centrifugal force in the impeller blades accelerates the gas outward and the pressure increases. Every rotation adds kinetic energy, resulting in further increase of pressure along the side channel. The side channel narrows at the rotor, sweeping the gas off the impeller blades and discharging it through the outlet silencer where it exits the pump.
