It separates entrained air from circulating fluid and allows that air to rise and exit through a connected air elimination device. The cast iron body provides long-term durability in closed-loop applications. The 3\/4 inch FNPT connections allow for straightforward in-line installation on the system piping. Licensed plumbers and hydronic heating technicians are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis air separator is suited for residential and light commercial closed-loop hydronic heating systems. It fits into the supply or return piping where air accumulation is a concern. By continuously separating air from the circulating fluid, it helps reduce corrosion and noise caused by air pockets and supports stable system pressure and heat transfer performance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInline design integrates directly into hydronic system piping without requiring a bypass loop\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch FNPT connections for standard pipe thread installation\u003c\/li\u003e\n  \u003cli\u003eCast iron body for durability in closed-loop heating applications\u003c\/li\u003e\n  \u003cli\u003eAllows separated air to rise and vent through a connected automatic air vent or air elimination device\u003c\/li\u003e\n  \u003cli\u003eHelps reduce corrosion and noise associated with air entrainment in hydronic circuits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation air separator for closed-loop hydronic heating systems using 3\/4 inch FNPT piping connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified hydronic heating technician in accordance with local plumbing codes and the system manufacturer guidelines. Shut down and depressurize the hydronic system before cutting into existing piping. An automatic air vent or manual vent cap must be installed at the top port of the separator to allow separated air to escape. Verify flow direction markings on the body before final connection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3\/4 inches FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Type\u003c\/strong\u003e: Inline\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Closed-loop hydronic heating systems\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: EMERSON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 49-075T\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EMERSON","offers":[{"title":"Default Title","offer_id":51346134532402,"sku":"49-075T","price":111.48,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555294.jpg?v=1782071681","url":"https:\/\/voomisupply.com\/products\/emerson-49-075t-inline-air-separator-3-4-in-fnpt-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
