Selecting a Roots vacuum booster

Review the GOFLEX VJP Roots vacuum booster models below as part of a complete vacuum system. A booster needs to be selected together with a suitable backing pump. Check the working pressure range, required pumping speed and permitted pressure difference for the proposed pump combination.

For selection support, send the chamber or process volume, starting and target pressures, required evacuation time and operating schedule. Use the vacuum pressure and units guide to state whether the starting and target pressures are absolute or gauge. Include gas composition, inlet temperature, existing backing pump details, voltage and frequency. Ask how the booster will be started, controlled and protected within the system.
