Pfeiffer DuoVane 22 – two-stage oil-lubricated rotary vane vacuum pump

The Pfeiffer DuoVane 22 is a two-stage oil-lubricated rotary vane vacuum pump. The nominal pumping speed is 19.5 m³/h (50 Hz) or 22.5 m³/h (60 Hz), the ultimate pressure 0.003 mbar. Rated motor power 0.55 kW (50 Hz) or 0.66 kW (60 Hz).

Features

• Powerful: according to Pfeiffer the best ratio of pumping speed to size in its class, fast pump-down from atmospheric pressure
• Efficient: according to Pfeiffer the lowest power consumption in its performance class, virtually maintenance-free
• Reliable: integrated gas ballast valve and optimised vacuum safety valve
