Leybold RUVAC WH / WHU 7000 Roots Vacuum Blower - REBUILT
The RUVAC WH and RUVAC WHU are Roots boosters driven by water cooled hermetically sealed motors. The WHU types have a pressure balance line between the discharge and intake flanges. The RUVAC WH and WHU are lubricated with synthetic oil or perfluorized polyether (PFPE). Only specially prepared RUVAC WH / WHU PFPE pumps can be used for pumping oxygen greater than atmospheric concentration. Only RUVAC WH / WHU PFPE pumps can be used for pumping very aggressive or hazardous gasses.
