Contractor Series Bath Fan Radiation Damper, NXCFRD Contractor Packs Save on energy costs byInstructions Many local codes require the installation of a ceiling radiation damper to protect the bath fan opening against the spread of heat and fire through the ductwork. Installed between the housing and grille, the damper employs an insulation blanket that closes off the opening in an emergency by means of a heat sensitive fusible link. Our ceiling dampers meet UL Standard 555C and are labeled for use in fire resistive floor ceiling membranes.
