Fire Damper

Fire dampers are essential components in building ventilation systems, designed to prevent the spread of fire and smoke through air ducts to other areas. When the temperature inside the damper reaches 72°C, the spring-loaded protective mechanism activates, causing the damper blade to close and effectively preventing the fire from spreading to other rooms. The damper can also be controlled via a servo motor as part of an automated system.

In smoke dampers, the system sends a signal to the servo motor, which opens the damper to allow smoke to be expelled outside.

The housing and blade of the fire damper are made from 1.5 mm galvanized steel, while the valve lever is constructed from 5 mm galvanized steel sheet. Additionally, fire-resistant stone wool, 20 mm thick and with a density of 70 kg/m³, is used between the blade walls to enhance the damper’s fire resistance.
