Back to Fire Dampers
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.
