Fire Damper Cartridges for ducts with a small diameter
Fire damper cartridge is a compact fire-resistant product made for easy
installation in circular ducts with diameters up to 200mm. A rubber seal holds
it in place, and in case of fire the intumescent material expands to perfectly
seal the cartridge in place, thus preventing the propagation of smoke and
flames. Our suppliers have 2 versions; the standard fire damper cartridge and
the cartridge equipped with a finishing ventilation valve for installation at
duct ends. These products are always equiped with a fusible link and they are
available in 60, 90 or 120 minute fire resistance
versions.
