A fire safety damper prevents the spread of smoke and fire via ventilation and air conditioning system ducts in the event of fire. Such units are installed in ventilation duct channels which cross fire-separation walls and ceilings. The fire resistance rating according to EN 1366-2 is EIS 60 or EIS 120.
The PL series dampers are made in the general-purpose industrial version with a minimized variety of hardware components using low-alloy galvanized steel. The flap is made of fire-resistant material (vermiculite) with thermoexpansive fireproof sealing. The duct design implies two connection ports for integration into a ventilation duct (duct system).
