Gardner Denver offers the following products for the best in positive displacement and regenerative blowers:
The Elmo Rietschle compact rotary lobe blowers belong to the group of dry running positive displacement pumps. This means that there is no need for oil or grease in the compression chamber. Only gear box and bearings, which are separated from the pumping chamber, are oil lubricated. Two non contacting triple lobed rotary lobe rotors rotate against each other in the compression room.
The triple lobed rotors avoid pulsation problems. The air blowers are customized to cater for the varying demands of our customers' applications.
Some technologies are so good that it is hard to improve them. Side channel blowers from Elmo Rietschle 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. Noise levels have been lower than that of most other vacuum pumps and compressors. Side channel blowers are used for conveying gases and gas-air mixtures.
