BSK-J/EI90(G)
multi-blade

The multi-blade fire damper type BSK-J/EI90(G) is used to prevent fire and reduce smoke spreading
from one fire compartment to another through the air ductwork system which may penetrate fire
separating walls and floors.
According to standard EN 1336-2 they assure minimum 90 minutes reliable closing.
The multi-blade fire damper can mounted in vertical (in/on rigid and light walls) or horizontal (in/on
floor) position.

HOUSING
The housing of the damper is
made of 4 double-walled,
fireproof calcium silicate sides,
that are assembled with rivets
using corner braces. The
connecting frame is made of
galvanized steel.
T h e d o u b l e - w a l l e d ,
overlapping damper blades
with steel bracing are placed
with 150 mm step. The louvers
have the same movement
direction. The louvers are
embedded in a heat resistant
bush that is extruded in the
double-walled house.
The “cold” leakage (20 ºC) of
the house is ensured by the
heat stabilized, customized
rubber profile placed on the
lower and upper gap closings,
on the side panels respectively
on the out- and inside edges of
the leaves.

BLADE DRIVING:
The blade driving consists of
a rod that is connected to all
the blades . The blade driving
is placed inside the casing,
outside the airflow.

fire damper with BF 230-T actuator
The BSK-J/EI90 multi-blade fire dampers are installed on the protected space in wall, ceiling, or air
duct. When the ventilation system is working the dampers are opened default. In case of fire the
dampers close automatically.
The closing is done with the help of spring return motor. Taking away the actuating power from the
motor the spring resets the motor and brings the damper in closed position.
The interruption of the power supply can be done in two ways:
in case of fire the thermo sensor installed together with the motor at 72 °C interrupts the power
supply of the motor,
or the monitoring system interrupts the power supply of the motor.
The operability of the dampers can be checked with the test switcher mounted on the sensor. When
the power is switched off the damper must be closed. When the switcher is released the damper is
resettled in open position.
The spring return motor has position sensors, so it is possible to display the opened and closed
position of the damper (for example in monitoring system). The thermo electrical actuator is always an
accessory of the damper actuating motor.
The damper actuating motors are placed parallel with the direction of the airflow. The actuating motor
is protected with a casing against fire.
The damper can be mounted in the walling only when the thermo sensor and the motor are placed on
the upper part of the vertical side. As an option can be ordered an 100 mm extension element that
allows the installation in wider walling and if there is no other solution the placement of the thermo
sensor.

MOUNTING
BSK-J/EI90(G)/8
The A BSK-J/EI90 fire damper can be installed in concrete wall, lightweight wall, ceiling and outside
the wall in air ductwork.
horizontal mountingvertical mounting vertical mounting
The damper can be installed with horizontal or vertical shaft as well. The motor at vertical shaft position
can be at the top or bottom as well. The direction of the airflow is independent from the point of view of
operation, but it is advisable to place the servomotor and the control unit on the opposite side with the
expected fire.
The installation depth of the BSK –J/EI90 multi-
blade fire damper with the connection frame is
200 mm. The connection to the ductwork system
is done with a 30 mm MEZ flange that has 4 pcs
(ø9,1x19 mm) oval holes on the corners.
In the case of installation within a solid wall the
required minimal wall width is 100 mm
3
( density ≥ 500 kg/m )
In case of installation within a ceiling the
required minimal wall width is 150 mm
3
( density ≥ 600 kg/m )
In case of installation within a lightweight wall
the required minimal wall width is 100 mm
In plasterboard walls, traditional walls (brick,
concrete) the damper can be build up or
concreted, respectively with fire protection HILTI
or other equivalent material.

MOUNTING
In opened position the blades do not overhang
the housing of the damper. Any part of the
element (ex. grid louver) connected to the
damper should not overhang in the housing of the
damper in order to not obstruct the free
movement of the blades. The BSK-J/EI90 multi-
blade fire dampers can be built in independent
from the access direction of the motor. There is no
need of separately right or left hand version.
The servomotor is shipped with a connection
cable (approx. 1 m long, with free ends). The
servomotor is equipped with protection casing in
order to prevent damages. The thermal relay can
be fixed on the optionally ordered extension or on
the ductwork built before or after the damper. It is
FORBIDDEN to make a hole on the housing of
the damper in order to place the sensor!
Take care to avoid damages. If the connecting
surface is not flat or the connecting frame is not
rectangular, the damper can be stretched. When
installing even connecting surfaces and
perpendicular edges must be assured. After
installing the easy move must be controlled. The
damper must be installed with closed blades.
The contact with splashing or running water must
be avoided, therefore it must be protected (ex.
outdoors must be fitted with a protective roof
against rainwater). The special fireproof material
of the damper absorbs moisture. In case of
excessive moisture the material gets soft, cracks
can appear. These can cause the damage of the
damper.
If the damper gets wet after drying it can be
operated without any problem. The water
resistance can be increased if we coat the
fireproof insulation parts of the damper with
PROMAT 2000 impregnating material.
Recommended thermal insulation materials for
different installation modes:
HILTI fire protection board – CFS-CT B 1S
HILTI acryl fire protection paste CFS-S ACR
CONLIT Ductrock 90 mineral wool fire
protection board
ROCKWOOL Steprock HD mineral wool board
PROMATECT -H fire protection board
PROMASTOP-P fire protection paste

multi-blade fire damper
BSK-J/EI90(G) multi-blade fire damper
Pressure drop:
The calculation of the pressure drop
is done with the following formula:
Δp [Pa] - pressure loss
v [m/s] - air velocity on the
nominal section of the damper
-3
r [kg/m ] - air density
x [-] - resistance factor
2
A [m ]- free cross-section
3
V [m /h] - airflow
