• The casing is made of galvanised steel, and joined by
welding.
• The housing is made from galvanized steel. It has a
symmetrical design that allows wall mounting regardless
of air flow.
• The blade is made of ceramic material resistant to high
temperatures and abrasion.
• These dampers meet the conditions required for the
symbol (S) to cold smoke seal. In case of fire, smoke
poisoning is the leading cause of death.
• The airtightness to the passage of cold smoke is
achieved through a joint between the perimeter of the
housing and the blade. This design, together with the low
thickness of the blade, allow to minimize the pressure
loss..
• For high temperatures, the damper is equipped with an
expanding intumescent seal, forming a paste that prevents
the passage of hot air and smoke from one side of the
damper to another.
• A rubber sealing ring at both ends of the casing ensures
an airtightness between the damper and the ducts.
• The operating devices of the dampers is automatic
shooting by means of a thermal fuse calibrated at 72
°
C to
activate the closure when reaches that temperature. Reset
is manual except for motorized dampers.
• The fire dampers
FMC-EIS-120
work as a separator
between two sectors of fire and ensure the same fire
resistance that the structural elements of
compartmentalisation, which limits the risk of spreading
of fire by interior of the building.
• FMC-EIS-120 fire dampers are according with the
following standards:
