Part of the R45 series, it accepts supply pressures up to 150 psi and regulates output across a range of 0 to 125 psi, making it suitable for precision pressure control in compact installations. The unit flows up to 35 CFM and features an integral relief function that vents excess downstream pressure when the regulator is adjusted downward. The plastic body keeps weight low at 0.38 pounds. A licensed pneumatic technician or industrial mechanic is the typical installer.\u003c\/p\u003e\n\u003cp\u003eThe R45-03C is used in compressed air distribution systems where space is limited and a full-size regulator would be impractical. It connects via 3\/8 inch NPT ports, fitting standard compressed air branch lines and point-of-use applications such as tool drops, pneumatic control circuits, and light industrial automation. A 1\/4 inch gauge port thread allows a pressure gauge to be added downstream if monitoring is required, though no gauge is included with this unit. The regulator is rated for use in fluid service with compressed air only.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMiniature R45 series form factor for space-constrained panel or inline installations\u003c\/li\u003e\n  \u003cli\u003e0 to 125 psi output pressure range with up to 150 psi supply pressure\u003c\/li\u003e\n  \u003cli\u003e35 CFM maximum air flow capacity\u003c\/li\u003e\n  \u003cli\u003eBuilt-in relief function vents excess downstream pressure during setpoint reduction\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch NPT end connections for standard compressed air plumbing\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch gauge port thread for optional downstream pressure monitoring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with compressed air systems only.

Depressurize and lock out the upstream air supply before making any connections. Apply thread sealant appropriate for pneumatic service to all NPT connections. Do not exceed the 150 psi maximum supply pressure rating, and ensure the operating temperature remains at or above 40 degrees F.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R45\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRegulator Type\u003c\/strong\u003e: Miniature\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFluid Type\u003c\/strong\u003e: Compressed Air\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePort Size\u003c\/strong\u003e: 3\/8 inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Pressure Range\u003c\/strong\u003e: 0 to 125 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Supply Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Air Flow\u003c\/strong\u003e: 35 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\u003eModular Connection\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: 40 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.38 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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R45-03C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540315504946,"sku":"R45-03C","price":122.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f4769fd4f01352b18906435513fd83da.jpg?v=1785851994","url":"https:\/\/voomisupply.com\/products\/parker-r45-03c-miniature-air-regulator-35-cfm-150-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
