Brandschutzauslässe

Brandschutzauslässe, also known as fire dampers, are passive fire protection devices installed in HVAC (heating, ventilation, and air conditioning) ductwork. Their primary function is to prevent the spread of fire and smoke through ventilation systems from one compartment to another. When a fire is detected, typically by a fusible link or an electrical actuator that responds to heat, the fire damper automatically closes. This closure seals the duct penetration, maintaining the fire resistance rating of the wall or floor assembly through which the duct passes.

There are various types of brandschutzauslässe, including curtain-type, multi-blade, and control dampers. The selection of the appropriate type depends on factors such as the required fire resistance rating, duct size, airflow, and the presence of smoke control requirements. Installation must be performed by qualified personnel to ensure proper functioning. Regular inspection and maintenance are crucial to verify that the dampers operate correctly and are free from obstructions. Failure of a fire damper to close can lead to rapid fire and smoke propagation, significantly increasing the risk of life and property loss. Brandschutzauslässe are a critical component in building fire safety strategies, complementing active fire protection systems like sprinklers and fire alarms.
