WKP-O Multi-blade fire damper


The WKP-O multi-blade fire damper is designed for application in general ventilation systems as cut-off partition separating the fire-engulfed zone from the remaining part of the building (normally open). The purpose of this damper is to prevent the spread of fire, heat and smoke.

The WKP-O damper may also be used for a transfer function. The WKP-O dampers are designed, manufactured and tested in accordance with the following 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.”

The effectiveness of the dampers is confirmed by tests according to PN-EN 1366-2 “Fire resistance tests for service installations – Part 2: Fire dampers.”

The WKP-O fire damper is classified as tightness class C (housing tightness) on the basis of tests carried out according to PN-EN 1751 “Ventilation for buildings. Air terminal devices. Aerodynamic testing of dampers and valves.”
