Description
A fire and smoke damper is a safety device installed in HVAC ductwork where it passes through fire walls, floors and smoke barriers; on detecting heat or smoke it closes automatically to contain fire and smoke within one zone. MEK fire and smoke dampers, available from MEK Uganda, help protect occupants and property in commercial, industrial and public buildings.

Frequently Asked Questions
Where should fire and smoke dampers be installed?
At fire walls, floor penetrations, smoke barriers and other critical points in the ductwork, with clear access for inspection, testing and maintenance.
How is a fire damper activated?
By heat through a fusible link, by a smoke detector, or by an electrical signal from the building’s fire alarm system.
Which damper do I need for my building?
Selection depends on the application and the building codes that apply. A qualified engineer should confirm the type and rating; contact MEK Uganda for technical consultation.
