Laboratory vacuum pump RE 9

rotary vane

very high flow rates even at vacuum levels approaching ultimate vacuum high water vapor tolerance due to efficient gas ballast; very good ultimate vacuum even with gas ballast vacuum-tight at switch-off; external anti-suckback valve not needed large oil volume: Long intervals between oil changes ease of maintenance due to telescopic design Rotary vane pump in action The RE 9 is a single-stage powerful rotary vane pump for fast evacuation of vessels and at higher gas flow rates. Typical applications are freeze drying, fine vacuum distillation and drying ovens. The single-stage rotary vane pump RE 9 is also available in various packages with matching accessories such as exhaust filter FO and valve VS 25. Rotary vane pumps are used for a process vacuum of a few mbar to 10-3 mbar.
