It accepts a maximum supply pressure of 300 psi and delivers regulated output across a range of 0 to 180 psi, with a maximum airflow capacity of 800 CFM. The zinc body construction provides durability under continuous-duty cycling. A 1\/4-inch gauge port thread allows an optional pressure gauge to be added without additional fittings. Built-in relief function vents excess downstream pressure when the regulator is adjusted downward, protecting downstream equipment from overpressure events.\u003c\/p\u003e\n\u003cp\u003eThis regulator is suited for high-volume compressed air distribution in manufacturing plants, maintenance shops, and heavy trade environments where large-diameter supply lines and consistent pressure control are required. The 1-1\/4-inch NPT end connections accommodate main supply headers and branch feeds serving multiple tools or pneumatic actuators simultaneously. Modular connection compatibility allows integration into ARO\/INGERSOLL-RAND filter-regulator-lubricator (FRL) assemblies, making it practical for staged pneumatic system builds. Minimum operating temperature is 32 degrees F, making it appropriate for conditioned indoor and heated enclosure applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4-inch NPT end connections for high-flow main line or branch installation\u003c\/li\u003e\n  \u003cli\u003e300 psi maximum supply pressure with 0 to 180 psi adjustable output range\u003c\/li\u003e\n  \u003cli\u003e800 CFM maximum airflow supports large tools and multi-drop pneumatic systems\u003c\/li\u003e\n  \u003cli\u003eBuilt-in relief function vents excess downstream pressure automatically\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch gauge port thread for optional downstream pressure gauge addition\u003c\/li\u003e\n  \u003cli\u003eModular connection design supports FRL assembly integration\u003c\/li\u003e\n  \u003cli\u003eZinc body construction for durability in industrial environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with compressed air systems requiring 1-1\/4-inch NPT connections and modular FRL assembly configurations within the ARO\/INGERSOLL-RAND Super-Duty series.

Depressurize and isolate the air supply line completely before removing or installing the regulator. Apply thread sealant appropriate for compressed air service on all NPT connections and verify for leaks after pressurizing. Consult applicable OSHA pneumatic safety standards and the system manufacturer guidelines for pressure system work in your jurisdiction.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePort Size\u003c\/strong\u003e: 1-1\/4 inches NPT\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 Working Pressure\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0 to 180 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Air Flow\u003c\/strong\u003e: 800 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGauge Port Thread Size\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFluid Type\u003c\/strong\u003e: Compressed Air\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Function\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModular Connection\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Gauge Included\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: 32 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 10.75 inches L x 3 inches W x 5 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Super-Duty\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: ARO\/INGERSOLL-RAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R37571-300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARO","offers":[{"title":"Default Title","offer_id":67909485429042,"sku":"R37571-300","price":239.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a88d4b90f8d147f157642d1eeb817c60.jpg?v=1791187975","url":"https:\/\/voomisupply.com\/products\/aro-ingersoll-rand-r37571-300-air-regulator-800-cfm-300-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
