Vacuum regulators

Fluctuations in the vacuum level put the process-secure operation of handling systems at risk. FIPA vacuum regulators maintain a constant vacuum level, even in handling systems with varying porous workpieces and when vacuum supply fluctuations occur.


FIPA offers vacuum regulators with and without external leakage. Models with external leakage are suitable as safety valves in systems with oil-free rotary vane pumps and as emergency devices for vacuum tanks. A knurled screw is used to adjust the vacuum level, whereby if exceeded the vacuum regulator draws in outside air.

FIPA precision vacuum regulators are also suitable for measuring and testing applications.


Vacuum regulators with external leakage

Safety control valve particularly for oil-free rotary vane pumps

  • Setting a constant vacuum level when handling workpieces with varying porosities or leakage
  • Suitable as safety valve if dry-running rotary vane pumps are to run continuously at maximum vacuum
  • Control of vacuum through automatic venting when a preset vacuum level is reached
  • Manual adjustment via fine thread, mechanical opening via spring load

+Ordering notes

  • On request suitable as safety valve for side channel blowers to limit the max. vacuum level (diameter of regulator and blower inlet should be identical)

+Notes

  • Turn the knob towards the plus (+) to increase the vacuum threshold value at which the regulator will start drawing in outside air. Turn the knob towards the minus (-) to reduce this value.
