The special tests allow installation within rigid vertical wall, within plasterboard walls and within solid plaster stud partition walls with a minimum thickness of 100 mm with more dampers close to each other or even in contact with one another as well as in line assembly since there is no requirement of minimum distances of 200mm defined in EN 1366-2. They allow for maximum safety in the prevention of spread of fire within the buildings. Fire dampers series WK23 guarantee perfect insulation and seal from hot and cold smoke as demonstrated by the numerous tests carried out in accordance with EN 1366-2.
