What is a Fire Damper?
A fire damper is a passive fire protection device installed within the ductwork of heating, ventilation, and air conditioning (HVAC) systems. Its primary purpose is to prevent the spread of fire and smoke through ventilation ducts that penetrate fire-rated walls, floors, and ceilings.
When exposed to high temperatures, the fire damper's fusible link melts, causing the damper blades to close automatically. This creates a barrier that maintains the fire resistance of the building's compartmentation, preventing fire and smoke from spreading to other areas via the ductwork.
Fyrup provides commercial fire damper maintenance and fire and smoke damper repair services across London — covering offices, residential blocks, hotels, retail, healthcare, and education premises.
Regular inspection, damper maintenance, and repair of fire dampers is essential to ensure they operate correctly in an emergency. Building regulations require fire dampers to be tested annually to maintain building safety certification.

Types of Fire Dampers
Fire Dampers
Standard fire dampers close automatically when exposed to high temperatures via a fusible link. They are designed to prevent fire spread through ductwork and maintain compartmentation integrity.
Smoke Dampers
Smoke dampers are designed to prevent smoke migration through ductwork. They are typically motorized and linked to the building's smoke detection system for automatic activation.
Combination Fire/Smoke Dampers
These dampers provide both fire and smoke protection in a single unit. They include both fusible links for fire protection and motorized actuators for smoke control.

- Visual Inspection
