Rotary Lobe Blowers
These 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 blowers are customized to cater for the varying demands of our customers‘ applications.
