Fire dampers are passive fire protection products used in heating,
ventilation, and air conditioning (HVAC) systems to prevent the spread of fire
to adjacent rooms through the ductwork. A fire damper activates when the heat
from the fire causes the normal temperature of a room to rise. Their goal is to
restore the fire resistance grade of the penetrated wall and to prevent smoke
reaching other rooms. Fire dampers are distinguished by their degree of fire
resistance, by their aeraulic properties and by their ease of installation. They
can be equipped with different types of mechanisms, depending on the specific
needs related to the project or local regulations. Buildings around the world
are safer today thanks to fire damper technology. Whatever your dynamic fire
damper or H.V.A.C. needs are, look no further.
