Fire damper FOC-EIS / FMC-EIS / FSC SERIES

• 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. • 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. • 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.
