Elmo Rietschle 2BH1910-7HH37 Overview
The Elmo Rietschle 2BH1910-7HH37 forms part of the established G-BH1 range of side channel blowers, also commonly referred to as regenerative blowers.
The regenerative operating principle progressively increases pressure as air circulates around the side channel before discharge.
The two-stage regenerative design builds pressure progressively through the blower, providing higher differential-pressure capability without oil in the compression chamber.
This gives the model a useful operating range for machinery requiring comparatively high vacuum or positive pressure from a side channel blower.
With -440 mbar vacuum and +500 mbar pressure capability, this version provides symmetrical higher differential-pressure performance for demanding industrial duties.
The 2BH1910-7HH37 combines strong vacuum capability with pressure performance up to +500 mbar, placing it among the higher differential-pressure models in the G-BH1 range.
With a 20.0 kW motor, -440 mbar maximum vacuum and +500 mbar maximum pressure, the 2BH1910-7HH37 is positioned for higher differential-pressure industrial duties.
Because no oil is required within the compression chamber, the G-BH1 design provides clean operation with very little routine internal maintenance.
The 2BH1910-7HH37 is a two-stage model with a 20.0 kW motor and is capable of operating at vacuum levels up to -440 mbar or pressure levels up to +500 mbar, subject to correct system design and operating conditions.
This performance profile makes the 2BH1910-7HH37 suitable for higher differential-pressure industrial vacuum and pressure duties, with final blower selection dependent on the required operating point, pipework, duty cycle and process conditions.
Vacuum Pumps UK can assist with the supply of new Elmo Rietschle 2BH1910-7HH37 side channel blowers for replacement and new equipment installations.
