Functional description
In the event of a fire, fire dampers shut automatically to prevent the propagation of fire and smoke through ductwork to adjacent designated fire compartments. In the event of a fire, the damper is triggered at 72 °C or at 95 °C (use in warm air ventilation systems) by a fusible link. The release mechanism is accessible and can be tested from the outside.
Construction with spring return actuatorFunctional description
The spring return actuator enables the motorised opening and closing of the damper blade; it can be activated by the central BMS. In the event of a fire, the damper is triggered thermoelectrically at 72 °C or 95 °C (use in warm air ventilation systems). As long as power is supplied to the actuator, the damper blade remains open. If the supply voltage fails, the damper closes (power off to close). Motorised fire dampers can be used to shut off ducts. The torque of each actuator is sufficient to open and close the damper blade even while the fan is running. The spring return actuator is fitted with limit switches that can be used for capturing the damper blade position.

Circular fire dampers for the isolation of duct penetrations between fire compartments.
Tested for fire resistance properties to EN 1366-2, with CE marking and declaration of performance according to the Construction Products Regulation.
Ready-for-operation unit, which includes a fire-resistant damper blade and a release mechanism. For mortar-based installation and dry mortarless installation into solid walls and ceiling slabs, mortar-based installation into non-load-bearing solid walls with flexible ceiling joint, mortar-based and dry mortarless installation into lightweight partition walls with cladding on both sides, lightweight fire walls and lightweight shaft walls, and dry mortarless installation on the face of solid walls. For dry mortarless installation in lightweight partition walls with metal support structure and flexible ceiling joint; for dry mortarless installation in solid walls and ceiling slabs when using a fire batt; in lightweight partition walls with metal support structure and cladding on both sides.
Casing length 400 mm, for the connection to ducts made of non-combustible or combustible materials. Thermal or thermoelectric release at 72 °C or 95 °C (warm air ventilation systems).
Constructions with spring return actuator for opening and closing the fire damper independent of the nominal size and even while the ventilation system is running, e.g. for a functional test.
Simple construction for dry mortarless installation with installation kit: ER, TQ, GL, WA

Während in der Vergangenheit die Öffnungen für den Einbau einer Brandschutzklappe in eine massive Wand oder Decke exakt und nur mit geringen Toleranzen geplant und ausgeführt wurden, können die Weichschott-Lösungen sehr viel flexibler gehandhabt werden. So wird die Montage in vorhandene Öffnungen möglich, die umlaufend um bis zu 400 mm größer sein können als die Gehäuseabmessung. Exakte Planungen der Einbauöffnungen sind damit nicht mehr zwingend erforderlich
