Fire dampers prevent the spread of fire by air conditioning and ventilation installations. They are installed in places of passage of ventilation ducts through walls and ceilings, which allows the division of the building into fire zones.
Construction:
The case is three-part, made of galvanized sheet. The partition and the inside of the damper are made of a special insulating material. There is an isolation trigger (fuse) with a melting point of 70 ° C or 120 ° C in the partition
Fire resistance and classification:
The PL-15 fire dampers have the EIS 120 fire resistance. They are certified in accordance with the PN-EN 1366-2 standard
The standard length of PL-15 rectangular flaps is 400 mm.
