Description
SMC AR30-N03-Z Air Pressure Regulator 7-125 PSI 3/8 NPT with Gauge
The SMC AR30-N03-Z is a general-purpose compressed air pressure regulator from SMC's AR series. It reduces and maintains a stable downstream pressure from a higher-pressure compressed air supply, using a top-mounted adjustment knob to set the desired output pressure. An attached SMC analog gauge displays output pressure in both PSI and MPa.

Applications
The SMC AR series regulators are widely used in industrial pneumatic systems to supply clean, regulated air at a consistent pressure to downstream equipment such as pneumatic cylinders, actuators, air tools, and process instrumentation. The AR30 size is suited for medium-flow applications in manufacturing, assembly automation, and machine tool environments. The 3/8 NPT porting is standard for mid-range pneumatic circuits, and the integrated gauge provides at-a-glance pressure confirmation without a separate gauge port. SMC is one of the most widely specified pneumatic component brands in industrial automation globally, and AR-series regulators are common in production machinery across a wide range of industries.
This SMC AR30-N03-Z air pressure regulator has been inspected and is in good used condition. The body and adjustment knob show light surface wear consistent with prior industrial use, and there is some patina on the brass elbow fitting at the gauge port. The NPT port threads appear clean and undamaged, as shown in the close-up photo. The included SMC pressure gauge is intact and readable. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
