FluidReg® Regulator

Brand: Proportion-Air, Inc

The FluidReg® is an independent membrane regulator that can be installed in (virtually) every fluid or compressed air pneumatic system.

It delivers a constant and consistent outlet pressure regardless of input pressure fluctuations.

The FluidReg is tamper proof, meaning the output pressure is pre-set at the factory and cannot be modified, adjusted or changed once installed.
