SMC Corporation NAR3000-N03 Pneumatic Regulator Assembly

SMC NAR3000-N03 Pneumatic Regulator Assembly is a modular regulator unit in SMC’s AR30/NAR3000 family, engineered to provide precise downstream pressure control for pneumatic systems. This unit uses 3/8 in NPT ports for both inlet and outlet connections and offers a regulating range around 7 to 125 psi, making it suitable for general automation and tooling applications that require stable air pressure. The NAR3000-N03 designation corresponds to AR30-series variants in which the regulator design enables modular integration with other SMC air-preparation components, allowing compact panel mounting and straightforward expansion with compatible regulators and filters. The AR30/NAR3000 lineage is illustrated by models such as AR30-N03H-Z-B (old NAR3000-N03), which share the same core specifications and porting configuration.
