Fire Dampers

Fire Dampers are used to prevent transmission of flame where air ducts penetrate fire barriers. A fire barrier is a fire-resistant-rated vertical or horizontal assembly of materials designed to restrict the spread of fire in which openings are protected. They can also be employed in air transfer openings in walls and partitions. Building codes specify where fire dampers are required. Fire dampers are available in two types, static fire dampers and dynamic fire dampers both round and square. (ul.com)
