2. APPARATUS
DESCRIPTION
2.1 GENERAL
Pro-Pak is an open circuit, self-
contained, compressed air Breathing
Apparatus (BA) for use by fire-fighters
and in industrial applications where a high
level of respiratory protection is required.
Standard versions of Pro-Pak feature a
mechanical pressure gauge and whistle
mounted on the left-hand shoulder strap.
Versions specifically intended for use by
fire-fighters are available which
incorporate the IRIS data-
communications system.
Pro-Pak is approved to the following
European Standards:
•EN 137 : 2006 - Including Annex A,
Self-contained Breathing Apparatus
classification: Type 2 - Fire
Fighting.
•EN 139 : 1995 - Self-contained
Breathing Apparatus with airline
attachment when there is no
intermediate split connection in the
MP airline between DV and
Pressure Reducer.
•EN 139 : 1995 - Excluding
requirements of clause 6.7.2, Self-
contained Breathing Apparatus with
airline attachment when there is an
intermediate split connection in the
MP airline between DV and
Pressure Reducer.

with EEC Directive EC/686/1986 plus
amendments.
Pro-Pak is approved to Australian/New
Zealand Standard AS/NZS1716 : 2003.
Please call Scott Health and Safety
Limited for further apparatus approval
details.
This manual contains user instructions for
single cylinder, twin cylinder (Duo)
versions and versions for use with
compressed air airlines.

H = Date of manufacture
I = Contact details of manufacturer
2.2 HARNESS
The Pro-Pak harness is made from
flame-retardant KevlarTM and NomexTM.
The buckles are manufactured from
stainless steel, chromium-plated steel or
brass; and the press-studs from brass or
nickel-plated brass.
For wearer comfort, a lumbar pad or full
back pad is provided. Both are fabricated
from flame-retardant material and packed
with flame retardant, closed cell foam.
The lumbar pad is held in place by four
press-studs. The full-length pad is held by
press studs and the harness straps.
2.3 CYLINDER BAND
Pro-Pak can be configured for use with
one or two (Duo) 200, 207 or 300 bar,
steel or fully wrapped aluminium carbon
fibre composite cylinders (see Table 3).
Cylinders are secured to the lightweight
back-plate by a webbing cylinder band
and a cylinder valve retainer (CVR).
The webbing cylinder band is secured
around the cylinder(s) by a hinged, clamp
mechanism with a thumb-operated
release tag that prevents accidental
opening. The band can be adjusted to
accept the range of cylinders listed in
Table 3. The clamp mechanism facilitates
replacement of similar size cylinders
without cylinder band adjustment.
Pro-Pak Duo cylinder bands can easily
be altered by the wearer (no tools
required) to mount a single cylinder,
centrally on the back-plate.
2.4 THE PNEUMATIC
SYSTEM
The pneumatic system has two pressure
reduction stages: air from the cylinder is
reduced to a medium-pressure (MP) of
between 5.5 and 11 bar by the reducer.
The second pressure reduction is
performed in the facemask Demand
Valve (DV).
Air from the cylinder passes through a
sintered bronze particle filter in the
cylinder connector, which protects the
pneumatic system, then through a short
length of high-pressure (HP) braided
hose to the reducer inlet manifold.

2.5 REDUCER
The reducer is a simple, self-regulating,
spring and piston device that requires no
adjustment. It has a pressure relief valve
(PRV) that protects the MP system from
over-pressurisation.
Air from the reducer is connected through
a reinforced, chlorinated polyethylene
hose to the facemask-mounted DV, which
regulates the air supplied to the wearer.
2.6 GAUGE AND WHISTLE
A high-pressure hose from the reducer
inlet manifold connects air, at cylinder
pressure, to a warning whistle and
pressure gauge.
On standard versions, the warning whistle
and pressure gauge are mounted on the
left-hand shoulder strap. On versions
fitted with the IRIS data-communications
system, the warning whistle and pressure
gauge are incorporated within the IRIS
unit.
The warning whistle sounds when
pressure in the cylinder falls to 55 bar (±5
bar).
The duration of the air remaining in the
cylinder, from the start of the warning
whistle, is listed for each cylinder type
under Warning Period in Table 3.
The pressure gauge dial is photo
luminescent to aid use in low light levels.
The lens is impact resistant
polycarbonate. A rubber shroud protects
the gauge.
Should the gauge, whistle or hose
become damaged, a restrictor in the
reducer limits air-loss to less than 25
litres per minute.
2.7 DEMAND VALVE
The DV operates in conjunction with the
facemask spring loaded exhale valve to
maintain a positive pressure within the
facemask.
The DV has a servo-assisted tilting
diaphragm mechanism that responds to
pressure changes within the facemask to
regulate the flow of air to the mask,
ensuring that pressure within the mask
remains safely above ambient.
The DV has a reset button that enables
wearers to close the airflow through the
DV, permitting the facemask to be
removed during test procedures and at
the end of a task, without loss of cylinder
air.
When the apparatus is donned the DV is
normally ‘reset’ (closed), and is opened
(activated) when the wearer takes a first
breath.
The DV has a supplementary flow device
(bypass), that the wearer can open using
the bypass knob.
When the bypass is used, the
unregulated flow of air through the DV
reduces cylinder duration.
The DV is connected to the facemask by
a Quick-Fit (QF) bayonet fitting with a
spring-loaded locking catch to prevent
accidental disconnection.

2.8 OPTIONAL
ATTACHMENTS
The available options are:
•Decontamination attachment (DCC)
- facilitates airline connection into a
gas-tight chemical suit, permitting
the wearer to breathe from an
airline during extended
decontamination procedures.
•Rescue mask attachment (RSM) -
permits the wearer to supply a
rescue mask or an air-powered
resuscitator from own cylinder air.
This reduces the duration of the
cylinder supply.
•Airline attachment (AL) - permits
Pro-Pak to be used with an airline.
The cylinder provides emergency
backup.
Note:
Air for use with airlines must conform to
Breathable Air as detailed in Section 1.
2.9 FACEMASKS

accommodate either one or two cylinders.
Conversion is a straightforward process
in which no tools are required.
To convert from Duo to single cylinder
application:
1. Remove both cylinders from the
back-plate as described in Section 3.3 of
this Manual.
2. Unscrew the central cylinder
connector from the Duo manifold. Store
the manifold safely for future use when
the Duo application may be required once
again.
3. Place the folding cylinder valve
retainer flat against the back-plate.
4. Rotate the fixed cylinder valve
retainer through 180o.
