• The casing is made of galvanized 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.
