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 pump chamber, are oil lubricated. The non contacting tripple lobed rotary lobe rotars rotate against each other in the compression room and avoid pulsation problems. The blowers are customized to cater for the varying demands of the customers applications.
