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. Both regular limit switches and explosion-proof limit switches are available for zones 1 and 2 (gases, mists, vapours) and for zones 21 and 22 (dusts) to indicate damper blade positions.
Construction with spring return actuatorFunctional description
The fire damper is used as a shut-off device to prevent fire and smoke from spreading through ducting in areas with potentially explosive atmospheres. The fire damper is suitable for supply air and extract air systems in potentially explosive atmospheres. For the operation of the fire damper, the operating and installation manual and the technical data in the supplementary operating manual must be observed.
Note: Upstream velocity for the explosion-proof actuator ExMax/RedMax-15-BF TR is ≤ 10 m/s
* Data applies to uniform upstream and downstream conditions for the fire damper
** Temperatures may differ for units with attachments; details for other applications are available on request.
Volume flow rate at differential pressure Δpst < 35 Pa

Circular fire damper with or without flanges, 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 into solid walls and ceiling slabs, and into lightweight partition walls and fire walls with cladding on both sides; for mortar-based installation in shaft walls with or without metal support structure and with cladding on one side; for dry mortarless installation in lightweight partition walls and fire walls with cladding on both sides.
Casing length 495 mm or 550 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.
