Elmo Rietschle 2BH1900-7AH17 Overview
The Elmo Rietschle 2BH1900-7AH17 forms part of the established G-BH1 range of side channel blowers, also commonly referred to as regenerative blowers.
Side channel operation generates vacuum or pressure through repeated acceleration of air around the blower casing.
Because no oil is required within the compression chamber, the G-BH1 design provides clean operation with very little routine internal maintenance.
The 2BH1900-7AH17 is a single-stage model with a 12.5 kW motor and is capable of operating at vacuum levels up to -290 mbar or pressure levels up to +280 mbar, subject to correct system design and operating conditions.
This performance profile makes the 2BH1900-7AH17 suitable for stronger 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 2BH1900-7AH17 side channel blowers for replacement and new equipment installations.
