Fire dampers FDC25/FDC40 are installed in ventilation ducts between re compartments in order
to stop the spread of re 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 re 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 gpsum
blocks wall
• Operating mechanism completely outside the wall
• Easy to install
• Maintenance free

As a safety element, the re 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 scaolding
• do not t 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, ocking, 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 re 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.

• Mounting is possible with the blade axis in horizontal or in vertical position
• The installation must comply with the tests that were performed during certication,
as 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 technical manual
• Operating temperature: 50 °C max
• For indoor use only
The FDC25/FDC40 re damper is always tested in standardized support frames (both in a concrete
wall and in a exible 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 re resistance
similar or greater than the one of the test.
