High-vacuum Pumping Units

High-performance, reliable vacuum equipment is essential for successful and time-saving work in many science laboratories. The VACUUBRAND high-vacuum pumping units satisfy these needs and fulfil practical requirements, while providing high vacuum to 10-6 mbar. These pumping units consist of an air-cooled diffusion pump, a two-stage rotary vane pump as a backing pump (either RZ 2.5 or RZ 6) and all connecting parts, including high-vacuum valve, ventilation valve and a bypass line. The pumping unit HP 40 B2 with RZ 6 provides higher pumping speed in the pump down phase and is additionally equipped with an oil mist filter FO.
