Inspection, Testing & Repair & Remedial Works

Fire dampers are crucial components of any building's ventilation system, designed to prevent the spread of fire and smoke through HVAC ducts. These dampers play a vital role in compartmentalizing the building, helping to contain fire within specific areas and providing valuable time for occupants to evacuate safely.

Key Features of Fire Dampers

3. Automatic Shut-Off: Equipped with cutting-edge technology, the dampers we supply automatically close when triggered by heat, smoke, or fire, preventing the passage of hazardous elements through the ventilation system.

The 4 Main Types of Fire Dampers

1. Single Blade Fire Damper: A single-blade fire damper consists of a single, movable blade or flap that automatically closes when exposed to high temperatures or when a fire alarm is triggered. The blade is typically constructed of fire-resistant materials such as steel or aluminium. When the damper is in the open position, it allows for the normal flow of air through the HVAC system, ensuring proper ventilation and temperature control.

2. Fire Smoke Damper: A fire smoke damper is a mechanical device used in buildings to prevent the spread of smoke and fire through the HVAC (Heating, Ventilation, and Air Conditioning) ductwork and ventilation systems. They are an essential component of fire protection and life safety systems. In the instance of a fire within a building, 44% of deaths are from outside the room of origin. 

3. Smoke Damper: The primary function of a smoke damper is to restrict or control the movement of smoke and hot gases in the event of a fire. When smoke is detected by a fire alarm or smoke detection system, the smoke damper automatically closes or opens, blocking the passage of smoke and fire from one area of a building to another. This action helps contain the fire and protect occupants in other parts of the building, allowing them more time to evacuate safely.

4. Mechanical Fire Damper: A mechanical fire damper is a safety device used in ventilation and air conditioning systems to prevent the spread of fire and smoke through ductwork in buildings. It is an essential component of fire protection systems, especially in large commercial and industrial buildings, where there are multiple zones or compartments that need to be isolated in case of a fire outbreak.

1. Repairs and Replacements: If any fire dampers are found to be faulty or non-compliant, we provide prompt repair or replacement services, helping you maintain a safe environment.

2. Upgrades and Retrofits: As technology evolves, so do fire safety standards. We offer upgrades and retrofits to bring your fire dampers up to the latest industry requirements.
