R-Series – Rotary Lobe Blowers

Rotary lobe blower R-VPA

Volume flow 430 to 3960 m³/hr 252.9 to 2329.4 cfm Pumpset consisting of a V-VWZ rotary vane and a rotary lobe pump. They combine the advantages of fresh oil lubricated vacuum pumps with the high suction capacity of a rotary lobe pump. Primarily used for generating fine vacuum in general industrial applications and for chemical processes. ATEX compliant versions are available on request.

R-VPA Datasheet

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.

Rotary lobe blower R-VPR

Volume flow 485 to 2752 m³/hr 285 to 1619cfm Ultimate vacuum of 0.01 mbar (abs) Pump set consisting of a V-VC rotary vane in combination with a rotary lobe vacuum pump. Primarily used for production of fine vacuum for general industrial applications.
