Fire dampers
FKR-EU
1
K4 – 1.1 – 34
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 in combination with
wooden beam ceilings and modular ceilings
(Cadolto system) as well as into lightweight
partition walls with one-sided cladding
(shaft walls) with or without metal support
structure. For mortar-based installation and dry
mortarless installation into lightweight partition,
fire walls, safety partition walls and walls to
provide radiation protection with metal support
structure or steel substructure as well as timber
stud walls and half-timbered constructions
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.
Explosion-proof constructions for zones 1, 2, 21
and 22 with limit switch or spring return actuator.
