Elmo Rietschle 2BH1940-7BH27 Overview
The Elmo Rietschle 2BH1940-7BH27 forms part of the established G-BH1 range of side channel blowers, also commonly referred to as Elmo regenerative blowers.
The blower develops differential pressure by accelerating air around the side channel in a dry-running, contact-free process.
Because no oil is required within the compression chamber, the G-BH1 design provides clean operation with very little routine internal maintenance.
The 2BH1940-7BH27 is a single-stage model with a 15.0 kW motor and is capable of operating at vacuum levels up to -130 mbar or pressure levels up to +110 mbar, subject to correct system design and operating conditions.
This performance profile makes the 2BH1940-7BH27 suitable for industrial vacuum and low-pressure air 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 2BH1940-7BH27 side channel blowers for replacement and new equipment installations.
