Abstract
本物品は、ダクトの開口部に設けられて火災発生時にダンパを閉じる防火ダンパであり、例えば使用状態を示す参考正面図に示すように、吸音ダクトの吹出口に取り付けられて、ヒューズ接続ワイヤが溶断すると、２枚のダンパが自動的に閉じられる。各ダンパは、グラスウールからなる吸音材を内蔵しており、底面側がパンチングメタルで覆われて構成されている。This product is a fire prevention damper that is installed at the opening of a duct and closes the damper in the event of a fire. For example, as shown in the reference front view showing the state of use, it is installed at the air outlet of a sound-absorbing duct and has a fuse connection wire. When the melt blows, the two dampers close automatically. Each damper has a built-in sound absorbing material made of glass wool, and the bottom side is covered with punched metal.
