Part of the R21 series, it accepts a maximum supply pressure of 300 psi and delivers regulated output across a range of 5 to 160 psi. The zinc body construction keeps weight low at 2.3 pounds while providing durable service in industrial and commercial pneumatic applications. With a maximum air flow rating of 117 CFM and 1\/4 inch NPT end connections, this regulator suits a wide range of supply line and tool-feed configurations. A built-in relief function vents downstream pressure when the set point is reduced, making pressure adjustments safer and more controlled.\u003c\/p\u003e\n\u003cp\u003eThe R21-02-000 is intended for compressed air service in industrial plants, commercial facilities, and mechanical rooms where downstream pressure must be held within a defined range. Typical installations include pneumatic tool supply lines, process air drops, and equipment protection applications where unregulated supply pressure would exceed safe operating limits. A licensed or qualified mechanic, pipefitter, or pneumatic systems technician handles installation in most commercial settings. The minimum operating temperature of 32 degrees F makes this unit suitable for indoor or climate-controlled environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDial air regulator with adjustable output range of 5 to 160 psi\u003c\/li\u003e\n  \u003cli\u003eHandles maximum supply pressure of 300 psi\u003c\/li\u003e\n  \u003cli\u003eMaximum air flow of 117 CFM supports high-demand pneumatic circuits\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch NPT end connections for standard compressed air piping\u003c\/li\u003e\n  \u003cli\u003eIntegrated relief function allows safe downstream pressure reduction\u003c\/li\u003e\n  \u003cli\u003eZinc body construction for lightweight, durable service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit regulator for compressed air systems requiring 1\/4 inch NPT connections and supply pressures up to 300 psi.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified pipefitter, pneumatic technician, or industrial mechanic familiar with compressed air system codes and safe practices. Depressurize and lock out the air supply line completely before removing any existing regulator or fitting the R21-02-000. Apply thread sealant appropriate for compressed air service to all NPT connections and verify there are no leaks before returning the system to pressure. The gauge port (1\/4 inch thread) is available for an optional pressure gauge if downstream monitoring is required.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRegulator Type\u003c\/strong\u003e: Dial Air Regulator\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R21\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePort Size\u003c\/strong\u003e: 1\/4 inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Adjustment Range\u003c\/strong\u003e: 5 to 160 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Supply Pressure\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Air Flow\u003c\/strong\u003e: 117 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Function\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGauge Port Thread Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Gauge Included\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFluid Type\u003c\/strong\u003e: Compressed Air\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: 32 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.3 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WILKERSON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R21-02-000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WILKERSON","offers":[{"title":"Default Title","offer_id":51538254627122,"sku":"R21-02-000","price":226.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1980dfbdec0e0b5d3c4bc88e23c5107e.jpg?v=1785820951","url":"https:\/\/voomisupply.com\/products\/wilkerson-r21-02-000-air-regulator-1-4-inch-npt-300-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
