NuVent MS Series Bath Fan Radiation Damper

  • SKU: NXMRD
  • Product Type: Residential
  • Barcode: 697453535700
Description

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.

Features:

  • Galvanized steel frame with insulation blanket constructed of non-asbestos, high-temperature reinforced fiber thermal curtain
  • Removable damper assembly and sleeve to allow for easy fan maintenance
  • Heat sensitive 165° replaceable fusible link
  • UL tested and labeled (UL Standard 555C) for use in 1, 2, and 3-hour floor-ceiling and roof-ceiling construction
  • Compatible with MS Series bath fans without built-in light
