{"product_id":"broan-rdm2-broan-nutone-r-radiation-damper","title":"Broan RDM2 Radiation Damper Other","description":"The Broan-NuTone® RDM2 Radiation Damper prevents the rapid spread of fire to other areas of a home during a fire. 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":44835797794952,"sku":"RDM2","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0616\/8756\/2376\/files\/RDM2-76365543.jpg?v=1780535728","url":"https:\/\/ktappliance.com\/products\/broan-rdm2-broan-nutone-r-radiation-damper","provider":"KT Appliance","version":"1.0","type":"link"}
