SMC 10-ARP20-02-3 | 10-ARP Series Clean Room Direct Operated Precision Regulator Body 20 1/4 Port Set Pressure Range 3

The SMC 10-ARP20-02-3 is a clean room specification direct operated precision regulator from the 10-ARP series, configured with body size 20 and 1/4 inch port connections for clean room pneumatic pressure regulation. This variant features the "-3" set pressure range option, providing a specific operating pressure window optimized for the application requirements. The ARP20 delivers setting sensitivity within 0.2% F.S. and repeatability within ±1% F.S. for precise, stable pressure output.

How does the 10-ARP20-02 with 1/4 port differ from the 01 (1/8 port) variant? The larger 1/4 inch port size supports higher flow rates with lower pressure drop across the regulator, making this configuration better suited for pneumatic circuits with greater air consumption or where multiple downstream devices share a single regulator. The larger port also reduces the risk of flow-induced pressure droop during peak demand events, maintaining tighter pressure stability under dynamic load conditions.

The ARP series is a modular style precision regulator with a locking adjustment knob that prevents accidental pressure setting changes. It reduces air consumption by up to 80% compared to conventional regulators (SMC comparison), delivering significant energy savings in continuous-operation clean room environments. The "10-" clean series specification ensures fluorine grease, controlled assembly, and anti-static double packaging.

This precision regulator is RoHS compliant and designed for integration into modular SMC air preparation assemblies. Suitable for semiconductor equipment, pharmaceutical process air, precision measurement, and any clean room application requiring stable, accurate pneumatic pressure regulation.
