Many codes require that exhaust fans installed in multi-family homes, with fire-rated ceilings, must be protected by radiation dampers. When the air temperature passing through the damper exceeds 165°F, the fusible link melts, triggering the thermal fabric to automatically close across the damper. Airflow is interrupted by a flame and heat barrier, preventing the rapid spread of fire to other areas of the home.","brand":"BROAN","offers":[{"title":"Default Title","offer_id":44300870516872,"sku":"RD1","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0616\/8756\/2376\/files\/RD1-76365552.jpg?v=1780531154","url":"https:\/\/ktappliance.com\/products\/broan-rd1-broan-nutone-r-radiation-damper-for-losone-select-r-ventilation-fans","provider":"KT Appliance","version":"1.0","type":"link"}
