Fire dampers are shutters in duct systems of air-conditioning devices that prevent spreading the
fire and combustion products from one fire segment to the other one by means of closing the air
duct in the points of fire separating constructions.
Dampers blade automatically closes air duct using a shutting spring.
The damper is sealed with a plastic foam packing against smoke penetration after closing the
blade. At the same time, the damper blade is bedded in a material which enlarges its capacity
and air´proofs the air duct.
Fire damper can be direcly equipped with a dish valve in both combinations - exhaust and
supply.
Damper characteristics
• CE certified acc. to EN 15650
• Tested in accordance with EN 1366-2
• Classified acc. to EN 13501-3+A1
• Fire resistance EIS 120, EIS 90, EIS 60
• Internal leakage class 2 acc. to EN 1751, external leakage is equal to ducting system
• Corrosion resistant acc. to EN 15650
• ES Certificate No. 1391-CPR-2018/0129
• Declaration of Perfomance No. PM/CFDM/01/16/1
Working conditions
Exact damper function is provided under the following conditions:
a) Maximum air circulation speed: 12 m.s-1
Maximum pressure difference: 1500 Pa
b) The air circulation in the whole damper section must be secured as steady on whole
surface.
Operation of the damper does not depend on the direction of air circulation. The dampers can
be located in an arbitrary position.
,
Dampers are suitable for ventilation systems, where air does not content any abrasive, chemical
or adhesive particles.
Dampers are designed for macroclimatic areas with mild climate according to EN 60 721-3-3.
Temperature in the place of installation is permitted to range from -30°C to +50°C.

Design with mechanical control
Design with mechanical control with a thermal protective fuse (inner mechanical control) which
actuates the shutting device within 120 seconds at latest after the nominal start temperature
72°C has been reached. Automatic initiation of the shutting device is not activated if the
temperature does not exceed 70°C.
By CFDM the design .01 with mechanical control can be equipped by one or two limit switches
signalling position of the damper blade "CLOSED". But in the case of the CFDM-V there is no
place to lead cables of the limit switches out of the duct - the dish valve is in the way.

Fire dampers are suitable for installation in arbitrary position in vertical and horizontal passages
of fire separating constructions. Duct assembly procedures must be done so as all load transfer
from the fire separating constructions to the duct in the placement of fire damper installation is
absolutely excluded. Installation gap must be filled by approved material perfectly in all the
installation space volume (installation gap).
To provide needed access space to the control device, all other objects must be situated at least
350 mm from the control parts of the damper. Inspection hole must be accessible.
Damper has to be accessible for regular checks and maintenance.
Fire damper is inserted inside the duct. Blade has to be inside of fire separating construction (after
closing).
The distance between the fire damper and the construction (wall, ceiling) must be at least 75 mm.
In case that two or more dampers are supposed to be installed in one fire separating construction,
the distance between the adjacent dampers must be at least 200 mm according to EN 1366-2
paragraph 13.5.

Examples of fire damper installing
The fire damper can be integrated into a solid wall construction made e.g. of normal concrete/
masonry, porous concrete with minimum thickness 100 mm or into solid ceiling construction made
e.g. of normal concrete with minimum thickness 110 mm or porous concrete with minimum
thickness 125 mm.
The fire damper can be integrated into a gypsum wall construction with fire classification
EI 120 or EI 90.
