KWP-P-E – rectangular duct smoke extract dampers
-
KWP-P-E – fire dampers are intended to installation in smoke and heat control systems, acting as protection against spreading of fire, temperature and smoke. During normal operation of the system , the flap of the KWP-P-E damper is in the open or closed position. In case of fire, the actuating system opens the dampers which operate in the fire detection zone (dampers in other zones move to the closed position). These dampers are nonsymmetrical, intended for vertical installation (in walls). They can be also installed in rigid building barriers. The damper is constructed, manufactured and tested in accordance with the standards: PN-EN 12101-8 “Smoke and heat control systems – Part 8: Smoke control dampers” and PN-EN 13501-4 “Fire classification of construction products and building elements Part 4: Classification using data from fire resistance tests on components of smoke control systems”. Sensitivity of the dampers is confirmed by tests in accordance with the standards: PN-EN 1366-2 and PN-EN 1366-10 “Fire resistance tests for service installations- Part 2: Fire dampers, Part 10: Smoke control dampers”.
