Description

 The fire damper made of galvanized steel sheet is applied to ductwork for breaking fires and smokes. It is a sort of strictly quality controlled volume control damper that can endure in the fire condition for 2 hours. When the temperature reaches 70^。C, it will automatically close and then there will be insignificant air flow or barely any airflow inside the ductwork, thus to obtain the fire prevention effect. The fusible link in the fire damper will melt in case of temperature rising or a fire, and the shutter will close. Our technical team with rich experience can design the most suitable air flow control solution tailored to your precise requirements.
