The Halton FEX fire dampers are type-approved class
H0(H120) fire dampers for use in offshore, nuclear
and navy ventilation systems. FEX dampers are used
to protect the integrity of bulkheads where they are
penetrated by ventilation ducts. The Halton FEX dampers
can be installed in rectangular or circular ducts. Dampers
have a fusible link and they prevent the spread of fire
and gases (low-leakage model) within the ventilation
ductwork. When the blades are in a open position, the
device does not cause significant pressure loss, noise or
flow disturbance. FEX dampers are set from outside and
are suitable to be installed in bulkheads. An open-closed
label is visible on the outside of the damper.
• Type approved by most recognized classification
societies, class H0(H120) fire damper when suitably
insulated
• Fixed frame and blades of stainless steel AISI 316L.
Painted frame surface as an option on request
• Weldings cleaned by acid treatment
• Lifting lugs as standard
• Blades contain thermal expansion seals
• Nominal release temperatures of fuses are 50 ºC, 74 ºC
and 100 ºC degrees. Other temperatures available
• Automatic electrical, pneumatic or spring operation
system available
• Maximum duct pressure 5000 Pa and maximum air
velocity 15 m/s

FEX PRODUCT OPTIONS
Halton FEX is available with following actuators:
• FEX-EL: Electrical spring return motor; standard
actuators being BF24 (AC 24 V 50/60 Hz DC 24 V),
BF230 (AC 230 V 50/60 Hz) or BF120 (AC 120 V
50/60 Hz). The motor contains built-in open-closed
limit switches. Separate junction box included in the
EL-model.
• FEX-PNR: Pneumatic rotating actuator. Junction box
available as an option.
• FEX-SP: Manual spring-actuated damper with fusible
link.
Ask more information for more actuators and
accessories.
OPERATION PRINCIPLE
In the event of a temperature rise in ductwork:
• FEX-EL: fusible link releases and cuts off operating
voltage to the spring return motor, allowing the
spring to close the damper blades. The fire damper
opens automatically when the fuse has been
changed and the operating voltage to the motor is reestablished.
• FEX-PNR: fusible link releases and cuts off operating
pressure to the spring return actuator, allowing
springs to close the damper blades. The fire
damper opens automatically when the fuse has
been changed and the pneumatic air supply is reestablished.
• FEX-SP: fusible link releases allowing the spring to
close the damper blades. When the fuse has been
changed, the fire damper must be reset into open
position manually.
