It combines air filtration with a built-in 90-degree transition to the furnace or air handler, reducing the number of components needed in tight mechanical spaces. The 28x40 inch footprint makes it a practical solution where conventional filter cabinets or separate transition fittings would consume too much floor space. HVAC technicians install this unit during new construction or retrofit work on upflow and side-return air handler setups.\u003c\/p\u003e\n\u003cp\u003eThe df12143 is suited for upflow furnace and air handler installations that require both a filter housing and a supply-to-return transition in a single assembly. It fits vertical, bottom air-return configurations where space is limited and a combined filtration and duct-transition solution simplifies the rough-in. It is commonly installed in residential applications where the air handler sits on a platform above the return-air plenum.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIntegrated 90-degree transition eliminates a separate fitting in the duct system\u003c\/li\u003e\n  \u003cli\u003e28x40 inch platform footprint accommodates common air handler base sizes\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for vertical, bottom air-return and upflow system configurations\u003c\/li\u003e\n  \u003cli\u003eSpace-saving design reduces installation time on side-drop and upflow applications\u003c\/li\u003e\n  \u003cli\u003eAccepts media-style filtration for improved particulate capture versus standard flat filters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style platform media air cleaner for vertical bottom air-return, upflow, and side-drop forced-air furnace and air handler installations requiring integrated filtration and duct transition.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Power to the air handler or furnace must be shut off at the disconnect before any work begins. Verify that the platform dimensions align with the air handler base and the return-air opening before securing the unit. Follow local mechanical codes and manufacturer clearance requirements for the connected equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlatform Size\u003c\/strong\u003e: 28x40 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Vertical bottom air-return with 90-degree transition\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Upflow and side-drop forced-air 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: RECTORSEAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: df12143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RECTORSEAL","offers":[{"title":"Default Title","offer_id":51267875045682,"sku":"DF12143","price":347.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308913167.png?v=1780692978","url":"https:\/\/voomisupply.com\/products\/rectorseal-df12143-platform-media-air-cleaner-28x40","provider":"Voomi Supply","version":"1.0","type":"link"}
