AR20S-50S, Standby Regulator

The AR20S-50S is a mechanical regulator that introduces a reduced standby pressure to the AMS. It features a simple locking knob to set an eco standby pressure and a non-relieving design, minimizing the volume of air required to bring the system back to full operational pressure. As a mechanical method to reduce air pressure during short idle times, it’s often purchased by facility engineers and managers looking for reliable, budget-friendly alternatives to digital controls.
