This essential component is designed for exhaust fans installed in multi-family homes with fire-rated ceilings, where codes often require radiation dampers for fire safety. When the air temperature passing through the damper exceeds 165°F, its fusible link melts, triggering the thermal fabric to automatically close. This action interrupts airflow with a flame and heat barrier, effectively preventing fire spread.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFor use in 1, 2 and 3 hour rated floor-ceiling and roof-ceiling constructions\u003c\/li\u003e\n  \u003cli\u003eGalvanized steel frame\u003c\/li\u003e\n  \u003cli\u003eHigh temperature, non-asbestos, reinforced fiber thermal fabric\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\n\u003cp\u003ePrevents fire spread in multi-family homes by automatically closing with a 165°F fusible link and thermal fabric.\u003c\/p\u003e\n\u003ch3\u003eProduct Information\u003c\/h3\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BROAN-NUTONE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: RDFUWT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Broan-NuTone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMPN\u003c\/strong\u003e: RDFUWT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 026715250929\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: UL Classified (UL-555C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Damper Accessory\u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"BROAN-NUTONE","offers":[{"title":"Default Title","offer_id":51306285007154,"sku":"RDFUWT","price":134.85,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309546894.jpg?v=1781288146","url":"https:\/\/voomisupply.com\/products\/broan-nutone-rdfuwt-radiation-damper","provider":"Voomi Supply","version":"1.0","type":"link"}
