Model RR-4 Redundant Regulator 

This regulator features a removable knob to render it tamper-proof. It features a 0-30 psi gauge, and when installed upstream of the pressurization unit, and is intended as an up-stream air supply safety device. This will satisfy NFPA 496 requirements for enclosure over-pressurization protection, for Best Purging Systems Model YZ101A, when the unit is installed without a Model PV Purge Vent.

Model RR-4 is also available with optional mounting hardware including a stainless steel mounting bracket, a regulator mounting ring, and stainless steel o-ring seal screws, gasket washers and nylon locking nuts, along with two 90 degree stainless steel elbow tube fittings to provide all essential installation accessories.
