Elmo Rietschle 2BH1 930 – side channel blower of the G-BH1 series
The 2BH1 930 is a side channel blower of the G-BH1 series from Elmo Rietschle. According to the data sheet, every G-BH type can be used as a vacuum pump and/or as a compressor in continuous operation over the whole range of the characteristic curve. Depending on the motor and mains frequency, a differential pressure of up to −340 mbar in vacuum operation and up to 370 mbar in pressure operation is permissible; the motor power is 8.5–21.3 kW at 50 Hz.Versions and motors
Listed are 32 order numbers from the Elmo Rietschle data sheets: three-phase and single-phase motors from the standard data sheet (without IE class); IE3 three-phase motors (60 Hz also NEMA Premium); high-temperature version with IE3 motors (characteristic curves for 160 °C inlet temperature). Voltage, current, power, permissible differential pressures, sound pressure level and weight are given with each version. Elmo Rietschle lists the versions with frequency converter in a separate data sheet; they are not listed individually here and are available on request.Volume flow
Elmo Rietschle gives the inlet volume flow of the G-BH types as a characteristic curve over the pressure difference (air 15 °C, 1013 mbar, tolerance ±10 %). According to Elmo Rietschle, the G-BH1 series covers 50 to 2,450 m³/h. Ehrler & Beck determines the volume flow for your operating point.Advice and service
