Fire damper WK43 SERIES

Overview Fire dampers Series WK43 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. Fire dampers are a series WK43 insurmountable barrier to the spread of fire, the heat transfer and spread of noxious fumes and gases through the seal tested for depression 300Pa as foreseen by EN 1366-2 standard. 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.
