SMC 10-ARP30K-N03BG-3Z | 10-ARP K Series Clean Room Direct Operated Precision Regulator Body 30 3/8 NPT With Backflow Function Gauge Bracket

The SMC 10-ARP30K-N03BG-3Z is a clean room specification direct operated precision regulator from the 10-ARP K series, combining body size 30, 3/8 inch NPT ports, backflow function, and an integrated round-type pressure gauge in a single modular unit. This fully-featured configuration delivers the complete precision regulation solution for clean room pneumatic circuits requiring accurate pressure control, visual monitoring, and safe depressurization capability without separate gauge installation.

How does the 10-ARP30K-N03BG differ from the N03B variant? The "G" suffix adds an integrated round-type pressure gauge to the bracket-mounted regulator body, providing immediate visual confirmation of outlet pressure at the regulator location. This eliminates the need for a separate downstream pressure gauge, simplifying the pneumatic circuit, reducing connection points (and potential leak paths), and improving operator accessibility for pressure verification during routine equipment checks and troubleshooting.

The body size 30 with 3/8 NPT ports handles mid-range flow demands, the "K" backflow function depressurizes downstream safely, and the precision regulation delivers sensitivity within 0.2% F.S. with repeatability within ±1% F.S. The ARP series reduces air consumption by up to 80% compared to conventional regulators, contributing to clean room energy efficiency targets.

The "10-" clean series specification provides fluorine grease, clean workshop assembly, and anti-static double packaging. RoHS compliant and designed for seamless integration with SMC's modular clean series air preparation ecosystem. The "-3Z" options complete the pressure range and accessory configuration.
