WKP-P Smoke control dampers
The WKP-P-E-J and WKP-P-E-W fire dampers are used in fire ventilation systems to prevent the expansion of fire, heat and smoke.
Classification of WKP-P-E-J Dampers in terms of fire resistance
The WKP-P-E-J dampers are classified in the fire resistance range indicated below and may be mounted in fire ventilation ducts.
E600 120 (ved -i o)S1000C300AAsingle
Classification of WKP-P-E-W Dampers in terms of fire resistance
The WKP-W dampers are classified in the fire resistance range indicated below and may be mounted in the following space dividers:
- EI 90 (Vew -i ↔ o)S1500C10000AAmulti
- EI 120 (Vew -i ↔ o)S1000C10000AAmulti
This class means that the automatically controlled damper installed in an isolating baffle keeps integrity, insulating and smoke leakage properties for at least 120/90 minutes; the class above also means that the damper can be operated remotely for at least 2 minutes from the moment of receiving the signal from the fire detector.
The WKP-P-E-W fire dampers may be installed in vertical space dividers with both horizontal and vertical axis of rotation of blades.
