The FBC1 FBC4 FBC7 series fire dampers, suitable for circular ducts up to diameter 200mm, allow maximum security in the prevention of spread of fire in buildings. They guarantee a perfect heat insulation and seal from hot and cold smoke as demonstrated by the various tests carried out in accordance with standard EN 1366-2.
They constitute a barrier from the spread of fire, transfer of heat and spread of harmful fumes and gases because of the use of the seal tested at 300Pa depression.
