1. product presentation
Fire dampers FD25/FD40 are installed in ventilation ducts between fire compartments in order to stop
the spread of fire and smoke trough the duct. They have a modular (manual or magnet) or motorized
mechanism, entirely outside the wall. Casing is made out of galvanized steel sheet, damper blade
is made of special insulating material, and damper blade shaft and push rod are made of stainless
steel. Bearings are made of brass, seals of polyurethane and elastomer. The fire damper can be
equipped with a simple mechanism with thermal fuse, or with solenoid actuator mechanism or with
electric actuator mechanism..
• Tested according to EN 1366-2 up to 500 Pa
• Airtightness according to standard EN 1751 class C
• Approved for installation in a concrete wall, a concrete slab, plasterboard wall and gypsum
blocks wall
• Operating mechanism completely outside the wallw
• Easy to install
• Maintenance free

circular connections
The circular connections are used to connect the circular ventilation ducts to the rectangular fire
dampers. When installing the connection plates, if the damper blade protrudes from the casing
(check dimension X> 0 - chapter 3 - Dimensions), it is very important to install an extension piece of
duct. The dimension X of the extension piece shall be calculated according to the equation X= (H-
370) / 2 (mm). The connecting plate is provided with a lip seal.

4. storage and handling
As a safety element, the fire damper must be stored, handled and installed carefully. Pay attention to:
• unload in a dry area
• avoid any shocks
• do not use the damper as a workbench or scaffolding
• do not fit the small dampers in the large one
The damper must be stored in a dry place, and kept out of water and frost. It should not be
stacked beyond the original packaging. It must be properly stowed so as to prevent any damage or
deformation resulting from an impact or high humidity. It must not be exposed to direct sunlight to
prevent premature aging of the thermal fuse. Once the damper is installed, the mechanism should be
kept away from any projections (cement, paint, flocking, water, dust) that may harm its operation. The
damper must be protected against the risk of heavy condensation.
The intumescent joints are essential for the fire resistance of the damper, all mechanical actions on
the refractory parts are to be excluded. All precautions shall be taken to ensure that premature aging
of the damper does not occur before it is actually installed. The actions of wedging and caulking
during the sealing of the dampers must not cause deformations that will alter the good functioning of
the damper and in particular the closing of the blade.

5. installation and implementation
5.1 installation
• Mounting is possible with the blade axis in horizontal or in vertical position
• The installation must comply with the tests that were performed during certification, s explained
in 8.2.
• Avoid any obstruction of the moving blade by the connected ducts
• The class of air-tightness is maintained in case the installation of the damper is made in
accordance with the tech
• nical manual
• Operating temperature: 50° C max
• For indoor use only
The FD25 / FD40 fire damper is always tested in standardized support frames (both in a concrete
wall and in a flexible wall) in accordance with EN 1366-2: 1999 table 3/4/5. The results obtained are
valid for all similar support frames which have a thickness and / or density and / or fire resistance
similar or greater than the one of the test.
