Fire damper

• • Summary of Fire Dampers:**

Fire dampers are devices designed to prevent the spread of fire and smoke in HVAC systems by blocking airflow during a fire. They come in two main types: mechanical and intumescent. Mechanical dampers operate through physical movement, while intumescent ones expand upon heat exposure to create a seal.

These dampers can also serve as air transfer fire dampers when used outside ducts, though modifications are often necessary for such applications. Compliance with safety standards is essential, involving regular inspections and adherence to testing protocols like UL555 and ASTM E2912.

Fire dampers play a critical role in fire protection by safeguarding building systems and ensuring occupant safety through effective smoke and fire containment.
