KMBD-BP Vacuum Boosters

Kinney vacuum boosters are automatically protected by an overload bypass valve which adjusts to gas load conditions.

When the pressure differential reaches a threshold of 75 Torr (100 mbar), the bypass valve opens to prevent further increase on the booster or the motor load. As the pressure differential reduces below threshold, the valve closes and the booster resumes normal operation.

The booster does not require variation in operation speed and the bypass valve eliminates the need for temperature or pressure switches.
