Our Custom Pressure Relief Dampers Ship Calibrated for Inert Gas Fire Suppression System Venting Applications
The BD-200-HD-FS Pressure Relief Damper
MAT’s fire-resistant, custom pressure relief damper is designed for inert gas and CO2 fire suppression system venting* and similar low back pressure applications that require specific opening pressures.
Built with the same heavy-duty construction as the BD-200-HD pressure relief damper, the BD-200-HD-FS is configured at the factory to open at designated pressures required during fire suppression system gas release.
