Elmo Rietschle 2BH1 490 – side channel blower of the G-BH1 series
The 2BH1 490 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 −170 mbar in vacuum operation and up to 160 mbar in pressure operation is permissible; the motor power is 0.95 kW at 50 Hz.Versions and motors
Listed are 5 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.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
