Overview

Fire dampers Series WK43 and WK45 ensure maximum safety in the prevention of the spread of fires within the buildings. Indeed they guarantee the perfect heat insulation and complete seal is to hot to cold smoke fumes as demonstrated by the numerous tests performed according to standard EN 1366-2 in the laboratories of CSI Bollate MI.
Fire dampers are a series WK45 insurmountable barrier to the spread of fire, the heat transfer and spread of noxious fumes and gases through the seal tested for depression 500Pa and 300Pa for WK45 WK43. By connecting the dampers to the fire alarm system and smoke detectors can anticipate the closing of the blade compared to the direct action of the flame and thus preventing the onset of indirect damage arising from the spread of smoke and gases generated by combustion.
