Systemair offers square fire dampers with a wide range of mechanisms and sizes for 90 and 120 minutes fire resistance. They are manufactured to comply with the latest European Standards, EN 1366-2 and EN 13501-3. All fire dampers are designed and certified for EI-S performance conformity. PK-I fire damper units are designed to be imbedded into horizontal or vertical rigid fire partition walls or vertical flexible fire partition walls. All units can be delivered as motorized with an actuator, manual or with electro-magnet release.
Fire damper casings are made of galvanized steel sheets and the blades are made of calcium silicate boards (asbetstos free). Each fire damper has a mechanism which can be electrical 24V, 230V, manual or with electro-magnetic release.

The dampers can be supplied with supply- and control uniys BKN or communication units BKS mounted on the damper.
The function of the fire damper is to stop the spread of fire, flames and smoke. Dampers with fusible link remain in an open position until the fuse is broken when reaching 72°C ± 1,5°C. After reaching this temperature the blade closes. Electrical actuators can also close the blade when called upon from a control system or BMS system, for example through the use of smoke detectors.
Controls (KSUA, KSUB, SUSB etc.).
Fire dampers are installed into fire safe partition walls and ceilings and are connected directly to the duct.
