What is the primary purpose of springs in a dynamic fire damper?

The primary purpose of springs in a dynamic fire damper is to force the damper closed against air flow. In the event of a fire, it is crucial to prevent smoke and flames from traveling through the ductwork, which is where the fire damper plays a critical role. When a fire is detected, the spring mechanism activates to securely close the damper. This closure is essential for maintaining the integrity of the fire barrier and limiting the spread of flames and smoke, thus ensuring safety within the building.

While there are various functions associated with the installation and operation of dampers, such as supporting the damper in a closed position or aiding with installation, the primary focus of the spring mechanism is its role in closing the damper effectively and reliably when it is needed most.
