Fire & Smoke Dampers

Fire Dampers – Fire Seal Curtain

The Holyoake IBD-FS fire seal curtain-type fire dampers are designed to preserve the integrity of a building while allowing air distribution systems to function seamlessly. These dampers facilitate the passage of air while effectively containing fire, smoke, and toxic gases. Featuring interlocking galvanised steel blades and stainless steel side seals, these dampers are housed within a galvanised steel guide channel frame. This compact design minimises space requirements and ensures straightforward installation in ductwork.

IBD-FS Fire Dampers Rating
