A60 Marine
Fire Damper
With ATEX rated
Pneumatic
(Hytork) Actuator
1. Description
The actionair Marine Fire Damper is tested and approved for
fitting to class A-0 A-15 A-30 A-60 divisions (bulkheads and
decks), when suitably insulated.
A-0 does not require any insulation to the casing.
2. Tests, approvals and certification
Lloyds Register Approved.
DNV-GL Approved.
ABS Approved
USCG Approved.
Transport Canada approved.
MED Marine Equipment Directive Compliant.
Fire tested to the latest IMO FTP code & in compliance
international convention for the safety of life at sea (SOLAS)
Sira certification (Ex) category 2 equipment
Corrosion Tested - EN60068-2-52 severity 2 conditions
Vibration Tested – EN60068-2-6 (5Hz to 350Hz @2g)
3. Health and Safety
Care must be taken when installing and inspecting dampers,
as they are likely to close without warning due to loss of
electrical power, or a temperature rise in the ductwork. This is
their prime function.
Do not introduce any items, fingers or limbs between the
blades.
Larger dampers are heavy and must be handled in accordance
with current local regulations and good practice.
All wiring should be carried out in accordance with the wiring
details provided, to the IEC regulations.
4. General Information
The actionair Marine Fire Damper is suitable for both vertical
and horizontal applications, with airflow in either direction.
The dampers tested to IMO fire test procedures Code, Annex 1
Pt 3, are normally open, and fail-safe to the closed position. The
actionair Marine Fire Dampers are supplied with the blades in
the fully interlocked closed position to avoid damage during
transit and installation. It is recommended that the dampers
remain closed until actual date of commissioning. All fire
dampers are life safety products and must be treated with care
during handling, storage and installation.
Actionair Marine Fire Dampers are designed for applications in
normal dry filtered air systems and should be subjected to a
planned inspection programme.
5. Installation - see below.
6. Maintenance & Cleaning
Dampers are supplied in two casing and blade material
options: -
Galvanised Steel casing and 430 Stainless steel blades, only
suitable for installation in dry filtered systems.
316 Stainless steel casing and blades and drive - more suited
for corrosive conditions, but even this will rapidly corrode and
fail if not properly maintained, when used in air intake systems
at sea. The addition of a mist eliminator is highly recommended,
and access must be provided for maintenance.
7. Testing
Two levels of testing exist.
Routine testing - Monthly, or in accordance with maintenance
programme, release and reset damper (via control system or
ETR test switch). Check remote indication or visual check of
mechanical pointer as appropriate.
Visual check at damper - At commissioning and at least once
a year, check damper operation by removing and
re-applying power to actuator. (via ETR test switch).
Visually check blades for damper closed and open positions.
Prove remote indication if applicable.
8. Routine Maintenance
Depending upon environmental conditions, each damper will
merit its own cleaning regime. Particularly hostile areas.
‘Frequency of maintenance’ should be determined by
collecting historical data from previous visits, and for this
reason, commence maintenance programmes.
Dampers in ‘Dry Filtered Air’ require very limited maintenance.
When exposed to fresh air intakes and/or inclement conditions
this may require monthly cleaning and lubrication maintenance
to be performed.
9. Cleaning
Using light lubricant, clean all exposed surfaces, using a cloth.
Remove all traces of surface staining, as this will deteriorate
further causing deeper material corrosion.
For 316 stainless steel blades and case, pay specific attention
to the blade rivets where crevice corrosion will cause rapid
failure of blades if not kept in check.
If damper is stiff to operate lubricate blade ends, open and
close damper successively until the damper moves with ease.
(This may necessitate removal of the actuator and operating
the blades manually by the drive shaft).
Refit actuator and re-test.
Clean off excessive lubricant.

10. Damper installation
All installations shall be carried out in accordance with the
relevant Marine/Offshore Authority requirements.
The damper should be installed in accordance with Insulation
details that represent a typical installation.
Please refer to the relevant notified body certificates for
insulation lengths located on Actionair website:
https://www.actionair.co.uk/products/a60-marine-damper
Bolt holes provided as standard on the damper flanges (unless
otherwise stated) at 150mm maximum centres. Matching hole
positions are necessary on mating coaming/duct flanges.
Apply approved fire-resistant sealant/gasket to mating flanges
and position damper.
Bolt A60 square/rectangular dampers using suitable steel bolts
minimum M8 diameter and minimum M6 diameter on A60
circulars.
Important:
For insulation lengths ** please refer to the relevant notified body certificates located on
Actionair website: https://www.actionair.co.uk/products/a60-marine-damper

11 Actuator Installation:
The actuator mounting plate is used also as a transit plate
prior to fitting of the actuator on site. The transit plate keeps
the damper blades closed by retaining the damper drive
shaft in a fixed position. When the plate is removed the drive
shaft is not secured.
Remove the 2No cross-recessed (Pozi) head screws
retaining the transit plate and discard the screws.
Using the 4No socket head cap screws supplied (M8 or M6
for HYTORK or FESTO actuators respectively), fit transit plate
(hereafter referred to as the mounting plate) to the
actuator.
Refit mounting plate to damper casing or bracket,
(whichever is the case) using 4No steel rivets supplied,
ensuring that the 4 holes in the damper casing line up with
the appropriate slots in the mounting plate (Marked ‘X’ on
figure 7, below).
*IMPORTANT* - please ensure damper blades are in the
fully closed position prior to mounting actuators. Failure to
do so may damage drive shafts and render the damper
inoperable.
12. Pneumatic Thermal
Release (PTR):
The PTR assembly is a special purpose design and is
supplied with necessary tubing that connects to the quick
fit couplings of the PTR and actuator. The PTR coupling
must not be disassembled, and the appropriate size tubing
must be connected to ensure correct operation.
