SMC 10-ARP30K-N03B-3Z | 10-ARP K Series Clean Room Direct Operated Precision Regulator Body 30 3/8 NPT With Backflow Function Bracket

The SMC 10-ARP30K-N03B-3Z is a clean room specification direct operated precision regulator from the 10-ARP K series, configured in the mid-size body 30 with 3/8 inch NPT port connections and integrated backflow function. The body size 30 provides increased flow capacity compared to the body 20, supporting pneumatic circuits with higher air consumption while maintaining the same precision control characteristics: setting sensitivity within 0.2% F.S. and repeatability within ±1% F.S.

When should you select body size 30 over body size 20? Body size 30 (ARP30) handles higher flow rates with lower pressure drop, making it the appropriate selection when regulating air supply for larger cylinders, multiple downstream devices sharing a common regulator, or applications where peak flow demands would cause unacceptable pressure droop through a body 20 unit. The 3/8 NPT port ("N03") further supports this higher-flow configuration with reduced fitting restriction.

The "K" backflow function exhausts downstream pressure reliably when set pressure is reduced, while the "B" bracket mounting and "-3Z" options complete this configuration. The ARP series reduces air consumption by up to 80% versus conventional regulators, delivering significant energy savings in continuously operating clean room compressed air systems where multiple regulators may be deployed across equipment groups.

The "10-" clean series ensures fluorine grease, clean room assembly, and anti-static double packaging. This precision regulator is RoHS compliant and designed for modular integration with SMC clean series filters, mist separators, and speed controllers.
