Fire dampers type KTS are designed for installation in ventilation systems as shut-off partitions separating the fire-affected area from the rest of the building. KTS type valves are shut-off (normally open), symmetrical, designed for horizontal buildings (in walls) and vertical ones (pillars). They can be installed in all types of building partitions (rigid partitions) together with plasterboard walls.

The main function of KTS type dampers is to stop the spread of fire, temperature and smoke. The dampers comply with the European classification PN-EN 1366-2.
