OVERVIEW
Description
Fire dampers WK45 are devices for use in heating, ventila-
tion and air-conditioning (HVAC) systems at re bounda-
ries to maintain compartmentation and protect means of
escape in case of re. They satisfy integrity, insulation and
smoke leakage criteria for the declared time of re resist-
ance.
Tested and classed in accordance with EN 1366-2 and EN
13501-3 regulations with 500 Pa depression (300 Pa for in-
stallations with Weichschott sealing).
Studied and optimized for medium and big size ducts fo-
cusing on aeraulic and acoustical performance.
Equipped with various dierent mechanisms completely
outside the wall, easily interchangeble even after installa-
tion.
General characteristics
• Casing made from galvanized carbon steel.
• Intumescent sealing gasket.
• Opening/closing mechanism with IP42 protection box
(IP54 for motorized version).
• 40 mm thick closing blade made with refractory material.
• Cold smoke air seal gasket
• Internal intumescent gasket for hot smoke seal.

Fire dampers pairing
The WK45 patented rectangular re dampers can be
paired side-by-side or vertically (not more than two) using
the custom connection kit (see section Accessories and
spare parts p.45). Two insulating layers must be inserted
between the two re dampers.
The pair of dampers, may be installed in vertical wall in the
same way as a single damper.

5. Magnet knob (for magnetic version)
6. Closed blade indicator
7. Open blade indicator
8. Manual closing button
Blade closing mode
Automatic closing with thermal fuse.
The control mechanism has a thermosensitive element
that automatically closes the blade when the temperature
in the duct exceeds 70°C (or 95°C for the re damper with
95°C thermal fuse).
It is possible to close the damper by pressing the indicated
button.
If the manual mechanism is equipped with electromagnet
it is possible to remotely close the re damper.
The manual command mechanism with magnet is
equipped with an electromagnet which, in case power is
interrupted (interuption magnet version) or when power
is supplied (input magnet version), comands the closing of
the damper.
Blade opening mode
The damper must be opened when the ventilation system
if switched o.
In case of closed damper by pressing the closing button or
remotely by electromagnet (magnetic version), it is possi-
ble to manually open the re damper blade by rotating the
lever antyclockwise.
For power supply interruption electromagnet, provide
power supply and pull the magnet knob before opening
the re damper.
In case of closed damper as a result of the action of the
thermosensitive element, it is possible to manually reopen
the damper by rotating the lever counterclockwise once
the element has been replaced.
Position indication microswitches
On request, the re damper can be supplied with posi-
tion microswitches (SA/SC/S2 optional) that signal the
blade position (open or closed). Refer to Electrical connec-
tions p.30 paragraph for more details.
Closing by remote control

the damper in open position operate on the lever indicat-
ed in gure.
For VGB/DGB versions to hold the damper in open posi-
tion, carefully rotate the handle counterclockwise.
During the manual opening of the damper, power must
not be supplied to the motor.

INSTALLATION
The sizes shown are in mm.
It is recommended to perform a functional test before
Installation to exclude possible damage during transport
and another test immediately after installation to exclude
accidental damage to the product and interference with
mounting components.
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.
The double test (with the mechanism inside and outside
the re area) demonstrated that there is no preferred direc-
tion for the position of the damper, both in relation to air
ow and the side with the higher probability of exposure
to re, as indicated in standard EN1366-2:2015 (paragraph
6.2).
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. WKGY100 xing brackets (accessory to order separately, one size
valid for all re dampers kind)
WKGY100 xing brackets are obligatory for intallations
within plasterboard walls and suggested for walls with 100
mm thickness.
They are not usable for installations with Fire Batt (Weich-
schott) sealing.
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.
WK45
15/56

INSTALLATION
WK45
16/56
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.

Transfer Application (application not connected to air ducts on one or both sides)
Following tests performed as per EN 1366-2, section 6.3.6 Standard, it is possible to install the re damper free from air duct
from one or both sides.
• Attention: re resistance classication for transfer appli-
cation is conform to section Fire resistance classication
according to EN 13501-3-2009  p. 9limited to EI 120S
if the ducted classication is higher.
• End cap with mesh shall be mounted on the side not
connected to air duct.
• End cap with mesh is made from galvanized steel sheet
and includes nuts and screws for xing on re damper.
• End cap with mesh is supplied loose from the re damp-
er.
