Some technologies are so good that it is hard to improve them. Elmo Riestchle regenerative blowers, also known as side-channel blowers, are such an example. They have proven their reliability in service for many decades, performing flawlessly day in and day out with virtually no down time. Our blowers can produce noise levels lower than that of most other vacuum pumps, centrifugal blowers and compressors.
The G-Series regenerative blowers feature NEMA Premium motors with voltage ranges for 50 and 60 Hz in protection class IP 55 (insulation class F) and are UL 507 and CSA 22.2 No.113 approved. This makes them the ideal solution for worldwide use.
With a height and width of approximately 4.9 inches and a depth of approximately 2.4 inches, the G-BH1 00 blowers are the smallest regenerative blowers available on the market.
With their high inlet volume flow up to 1,413 cfm and a differential pressure of up to 313 in. H₂O, our low noise G-BH1 regenerative blowers have earned their reputation. They are reliable, low maintenance and durable. They deliver 20,000 operating hours between service and are virtually maintenance free.
Volume flow up to 520 cfm and differential pressure up to 420 in. H₂O. With its significantly expanded range of performance and lower noise levels, the regenerative technology can now be used in completely new fields of application that were previously inaccessible. They deliver 40,000 operating hours between service and are virtually maintenance free.
Our high performance G-BH7 regenerative blowers can create differential pressure of up to 435 in. H₂O. They deliver 20,000 operating hours between service and are virtually maintenance free.
Our German developed 2BH8 series of regenerative blowers have capabilities upwards of 400 in. H₂O, with maximum flow capacities at just over 450 CFM. These tried and true blowers can operate up to 20,000 hours before needing serviced, operating virtually maintenance free.
Our regenerative blowers are available in a wide selection for performance ranges up to 1,766 cfm at 60 Hz and differential pressures of up to 420 in. H₂O. With flexibility and power, these blowers cover a variety of demanding applications, including high pressure and high flow applications.
The impellers in the G-Series machines are mounted directly on the motor shaft for contact free compression. Maximum reliability, even at high differential pressures and large volumes of air, is ensured by the arrangement of the bearings outside the compression chamber.
