YD-400S smoke dampers are dampers to be used for smoke evacuation. It is used for prevention and evacuation of smoke at high temperatures. They are wall type smoke evacuation dampers that directly opens to the fire conditions within the building.

And it is expected for the channels and other items -passing through different areas within the building- to be manufactured as being resistant to fire. In implementation with fans or with natural suction, the dampers that will be used in evacuation systems -which can be directly opened to shaft from the area of fire- are designed as to be opened during fire. Dampers within an area not being subject to fire are closed to prevent the dispersion of smoke to other floors.

And in cases when more than floor is being evacuated with a common fan, it shall be able to perform suction only from the area being subject to fire and to close the dampers of other floors.

Thus in corridor and shaft smoke evacuation systems, the operation of separating areas where YD-400S is applied provides advantage in respect of the system.

Technical Information :

• Full power of the fan focuses on the area of fire, thus fast smoke evacuation is ensured.
• The risk of penetration of smoke from other areas is being decreased by not creating the old pressure.
• As the depth of damper is narrow, it is easily used within the wall.
• It is preferred for narrow shafts.
• When the blades are at open position, they are parallel to each other.
• Body and blades are manufactured of galvanize.
• Non-corrosive body and blades can be used preferably in industrial implementations.
• Blades and body are resistant to fire for 2 hours.
• Low leakage class is 200 m³/h per m².
• Engine is within special protective casing, and it can be reached and maintained easily from the corridor side.
• Damper can changeover quickly with special spring loopback engine. (On/Off)
• The position of damper over the engine can be monitored easily through BMS.
• Corridor section, in order to be in conformity with architecture, is being used with specially designed vents and shutter accessories that do not prevent evacuation of smoke.
