KWP-O-E(S) – rectangular fire- and smoke dampers
-
KWP-O-E(S) – fire dampers are intended to installation in ventilation systems as cut-off baffles, separating the fire zone from the remaining part of the building. Therefore, the basic function of the KWP type fire dampers is to restrain the spreading of fire, temperature and smoke, and additionally, with use of appropriate actuators, to use in mixed ventilation systems (used not only in case of fire but for example: for periodic airing).
These fire dampers are nonsymmetrical, intended for vertical (in walls) and horizontal installation (in ceilings). They can be also installed in rigid building barriers. Fire damper is constructed, manufactured and tested in accordance with the standards: PN-EN 15650 “Ventilation for buildings – Fire dampers” and PN-EN 13501-3 “Fire classification of construction products and building elements- Part 3: Classification using data from fire resistance tests on products and elements used in building service installations: fire resisting ducts and fire dampers”.
Sensitivity of the fire dampers is confirmed by tests in accordance with the standard PN-EN 1366-2 “Fire resistance tests for service installations- Part 1: Fire dampers”.
