Fire dampers FD25/FD40 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 gypsum
blocks wall
• Operating mechanism completely outside the wall
• Easy to install
• Maintenance free

The circular connections are used to connect the circular ventilation ducts to the rectangular
re 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.
Lenght of damper blade outside of casing: X=(H/2)-175 (mm)

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 scaffolding
• 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, 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 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.

Prepare wall opening B (H) + 100 mm. Place re damper and duct on pre-cut calcium silicate 52mm
(Promat L500). 100mm wide supports from same material need to be used to support the duct as well
as the damper.
Fit the duct and the damper through
the wall, and cover them with 52 mm
calcium silicate (Promat L500). Board
corner joints must be glued with glue
PROMAT K84 and connected with
staples every 100mm
The gap between the damper and the
wall must be lled with mineral wool
(density 140 kg/m³ or more)
Close the mineral wool with
Promatect H plates 20mm thick.
Duct and damper supporting
brackets have to be insulated with
52 and 20mm calcium silicate boards
(Promatect H and L500) More detail drawing of installation
will be send upon request!

The wall is composed of 2x2 GKF plates, 12.5 mm thick, installed on a 48 mm wide steel construction.
The interior of the wall is lled with mineral wool of 100 kg / m³ density.
Recommended wall opening is
B,H+70 mm
Place ventilation duct trough wall.
Distance between suspensions se max.
800 mm (thickness of threaded rod for
suspension should be M12 or more)
Install re damper and secure it to
ventilation duct
Fill space between duct and wall
with mineral wool (Isover U protect).
Additionally paint wool with Isover
BSF in thickness of 1mm.
Close installation with L proles
30x30x3mm. Additionally x proles to
duct with self-tapping screws, and screw
them to wall with 4,5x50 screws. Repeat
the same procedure on the other side.
Install wool (Isover U protect). Wool
should be glued to the wall with
Isover BSK glue. Glue is applied in
thickness 2mm. For details please see
Isover U-protect brochure page 28.
Secure the wool with welding nails.
Nails are placed 60mm from the end
of the plate and 150mm between
each other.
Place the wool on ventilation
duct in lenght of 80m and scure it
withwelding nails.
In the corner are aditionaly used
IsoveFireProtectScrew screws on
every 150mm. Additionally place steel
protection on place where insulation
on damper ends.
