Rotary vane pumps from VACUUBRAND offer great performance in a compact design. Even with the gas ballast open, they enable a very good ultimate vacuum. You also benefit from extended oil change and maintenance intervals thanks to optimised lubrication circuit and large usable oil volume.

• High flow rates even at vacuum levels approaching ultimate vacuum
• 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

The one-stage RE 2,5 and two-stage RZ 2,5 are high-performance rotary vane pumps with extra compact design and low weight. They are the ideal solution for a wide range of laboratory and process applications that require low ultimate vacuum at medium gas flow rate. The RZ 2,5 is also available combined with the oil mist filter and the VS 16 valve as a package.

Typical applications are lyophilisation, fine vacuum distillation and evacuation of small volumes, e.g., for utilisation of µ-focus x-ray tubes or filling with pure gases.
