Intumescent Fire Dampers
Intumescent Fire Da
mpers are Passive fire dampers which expand to block their aperture upon exposure to elevated temperatures.
Intumescent fire dampers differ from regular fire dampers in that they have no moving parts; instead they expand to many times their normal size upon exposure to elevated temperatures indicative of a fire, forming an incombustible mass which seals its aperture, preventing the spread of fire and hot smoke.
