Intended use
The MP3 re dampers are “Devices for use in heating, ven-
tilation and air conditioning (HVAC) systems at re bound-
aries to mantain compartmentation and protect means of
escape in case of re”according to the 3.1 paragraph of EN
15650:2010 standard.
It is compulsory to install the re damper according to the
instructions indicated in the technical data sheet and man-
ual to maintain the declared performances and, in particu-
lar, the re classes.
Use permitted in any civil and industrial building.
Use permitted in saline atmosphere, for example:
• maritime and port enviroments;
• sh markets;
• slaughterhouses;
• cheese makers.
Not allowed uses
• Use with installations dierent to those described in the
technical data sheet and manual;
• use as smoke control damper;
• use as shut o damper;
• use in external environments without adequate protec-
tion from atmospheric conditions;
• use in explosive environments;
• use on board of ships;
• use in cooker extraction hoods;
• use in pneumatic conveying systems of dust or corn;
• use in ventilation systems within locations subject to
chemical contamination;
• use in non inspectable enviroments.
• Installation in suspended ceilings.
Blade rotation axis positioning
The re damper can be installed both with the blade axis
positioned vertically or horizontally.
Positioning brackets before xing
1. Positioning brackets
Installation of exible connectors in order
to balance out the ventilation ducts
expansion
CAUTION: Refer anyway to law and national standardiza-
tion�
Flexible connectors compensate any duct thermal expan-
sion and wall bending in case of re.
Flexible connectors are used to limit re damper stresses
due to external forces in case of re and to preserve re
resistance class.
In general it is always appropriate the use of exible con-
nectors for the followings installations:
– light walls;
– Plasterboard and rock wool or Fire Batt (Weichschott)
sealing;
– Applique xing system.
Flexible connector must be normal ammability and in
case of re the grounding bonding should disconnet to
guarantee the complete separation between re damper
and connected air duct.
When exible connectors made of conductive material
(e.g. aluminum) are used, no additional grounding bond-
ing is required.
Despite exible connector installation, the re damper
must be installed in the construction support so that its
weight does not aect damper’s installation position both
during normal operation and in case of re.
It is recommended not to compress exible connectors in
the installation phase.
Flexible connector must be at least 100mm long and in
order that possible duct thermal expansions are balanced.
Take care that the exible connector does not interfer with
opening / closing movement of the blade.
Refer to the section Technical data p.13 for blade expo-
sition values.

Construction supports characteristics
The European standard for re dampers foresees a precise
correlation between the wall/oor characteristics and the
re resistance class obtained, as well as the correlation be-
tween wall/oor used for the test and wall/oor used for
the actual installation.
The test results obtained on a type of wall/oor are valid
also for walls/oor of the same type but with greater thick-
ness and/or density than those used in the test.
For plasterboard walls, the test results are also valid for walls
with a greater number of plasterboard layers on each side.
As a result, the indicated thickness and density characteris-
tics are to be considered as minimum values.
The wall/oor in which the re dampers are installed must
be re class certied according to the standards foreseen
for the structure.
Rigid walls
Can be made with aerated concrete blocks, poured con-
crete, concrete panels, perforated cell elements in concrete
or brick in accordance with the following characteristics:
• minimum thickness 100 mm;
• minimum density 550 kg/m³.
The use of a reinforcing beam above the opening is recom-
mended for walls made from concrete blocks, bricks or in
concrete cell elements.
1. Reinforcing beam
Light plasterboard vertical walls
During testing, light plasterboard walls have been used
with the following characteristics:
• U-shaped horizontal metal frame (50 mm) and C-shaped
vertical frame (49 mm) made from 0,6 mm thick sheet
metal;
• Vertical proles placed with a maximum spacing of 625
mm between each other;
• Filling made of rock wool with density up to 100 kg/m³
(optional);
• Each side is made from two plasterboard layers 12,5 mm
thick, unalinged to avoid alignment between the joints
of the layer above and below.
The following indications are given for the installation walls:
• metal proles minimum width: 49 mm;
• metal proles minimum thickness: 0,6 mm;
• vertical proles placed with a maximum spacing of 625
mm between each other;
• vertical prole xing with selfthreading screws or by
clinching to the bottom horizontal prole and insertion
