Elmo Rietschle 2BH7 320 – side channel blower of the G-BH7 series
The 2BH7 320 is a side channel blower of the G-BH7 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 −540 mbar in vacuum operation and up to 890 mbar in pressure operation is permissible; the motor power is 1.3–2.5 kW at 50 Hz.Versions and motors
Listed are 9 order numbers from the Elmo Rietschle data sheets: IE3 three-phase motors (60 Hz also NEMA Premium). 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-BH7 series covers 50 to 230 m³/h. Ehrler & Beck determines the volume flow for your operating point.Advice and service
