C-C120 Circular Smoke Closures

DescriptionProtection against smoke spread, cold or hot smoke, occurs by closing the backflow dampers in the event of a change in airflow direction and preventing air and fire gases from spreading through the ventilation system.C-C120 is tested for ES criteria according to EN 1366–2. It closes instantly when the airflow is interrupted. It is fully self-actuated without any external input, thanks to balanced blades. This ensures reliable and economical smoke protection. It also stays closed in the event of a fire, which generates an overpressure in the affected zone.To improve the accessibility for inspection of the backflow closure a flexible duct coupling can be used, or accessory for inspection.Highlights• Performance of E120S• Cold-smoke prevention• Versatile - Any installation position• Stable performance, no oscillation (even in the cooling phase)• Low sound power level and pressure drop• Ecological - No power needed for activationFire ResistivityC-C120 smoke tight closure follows similar standards as Fire dampers. It is tested according to EN 1366-2:2015. As this product has not yet been covered by a harmonized standard, it follows classification according to EN 13501-3 + A1:2009.• Smoke tightness in operation following EN 13501-3 + A1:2009 at ambient temperature S (follow Product Handling & Application section)• Standard supporting construction in accordance with EN 1366-2:2015: up to E120 (ve ho)S (follow Installation section)DesignC-C120 closures have casings made from galvanized sheet metal. Blades are from stainless steel. On the perimeter intumescent seal is used, that expands in a fire situation. It is covered by glass-fiber material for better resistance and installation. Same material is used under the blades as a dampening stopper.Activation Types• The closure is fully self-actuating and does not require any airflow or pressure to close.
