VARIAIR U 5 Series - Oil Lubricated Rotary Vane Vacuum Pumps

The Becker VARIAIR U 5 Series vacuum pumps are deep vacuum, oil-lubricated rotary vane pumps with a frequency inverter. The robustly constructed rotary vane pumps are suitable for higher pressure differences in vacuum and/or pressure applications. An eccentrically mounted rotor with slots rotates in a cylindrical housing and the precisely fitting sliding vanes move in the slots and separate the individual working chambers. Compared to dry-running rotary vane pumps, oil-lubricated pumps additionally seal the working chambers with the oil that is also transported. The pumps are thus able to generate a fine vacuum and are therefore suitable for applications that require a high vacuum.

Each VARIAIR U 5 Series pump comes standard with:

• Most efficient IE3 motors in the industry
• High efficiency oil separator element
• Oil tank with dual stage oil separation
• Gas ballast valves available
• VARIAIR frequency inverter
