Product Description

Fire Damper is an important fire safety equipment, which is widely used in building ventilation and fire fighting systems. Here's a closer look at Fire dampers:

Definition and how it works

Definition: Fire Damper is a temperature-controlled valve of a memory alloy that is closed by the action of gravity and a spring mechanism (or memory alloy deformation). The main purpose is to stop the fire from spreading through the ventilation ducts by closing the valve automatically or manually in the event of a fire.

How it works:

Thermal principle: The Fire Damper is equipped with a thermal element that triggers the valve closing mechanism when the ambient temperature reaches a predetermined value (usually 70 ° C or 280 ° C), thereby preventing the spread of fire and smoke through the ventilation duct.

Mechanical closing: In some cases, the Fire Damper may also be triggered by an external force, such as a command from a fire alarm system, in a way that does not depend on changes in ambient temperature.

Application field

Fire Damper is widely used in various types of buildings, such as office buildings, shopping centers, hospitals, high-rise residential buildings, etc. It is usually installed in the key position of the ventilation system or fire smoke exhaust system, such as the air conditioning system, ventilation pipes, etc., to ensure that it can be closed in time in the event of a fire and prevent the spread of the fire.

To sum up, Fire Damper, as an important part of the fire safety system, plays an important role in protecting the safety of personnel and property in the building. Therefore, in the process of purchase, installation, use and maintenance, it is necessary to strictly comply with the requirements of relevant standards and specifications.
