This manual contains user instructions
for single cylinder, twin cylinder (Duo)
versions and versions for use with
compressed air airlines.
2.2 HARNESS
The Pro-Pak harness is made from
flame-retardant Kevlar
TM
and Nomex
TM
.
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
backplate 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 backplate.

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.

PRO-PAK
6
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 airline must conform to
Breathable Air as detailed in Section 1.
2.9 FACEMASKS
Pro-Pak is approved for use with:
Vision 3, PanaSeal, PanaVisor and
Pro-Mask PP full facemasks, all of which
conform to EN 136, Class 3.
All are available with five point, fully
adjustable web or net head-harnesses
and neckstraps.
An inner mask minimises CO
2
dead
space and visor misting. A speech
diaphragm is fitted.
PanaSeal is suitable for medium and
smaller face sizes. PanaVisor is suitable
for medium to larger face sizes.
Vision 3 is available in three sizes, small,
medium and medium/large which cover
most face sizes. Pro-Mask PP is

MONTHLY CHECKS
3.1 CHECK APPARATUS
Visually inspect to ensure that Pro-Pak is
clean and in good condition. Check that
all hose retaining press-studs or Velcro
TM
retainers are closed. Fully slacken the
waistbelt and shoulder straps ready for
use.
When Pro-Pak is to be used with an
airline check that:
i) The airline is in good condition, free
from splits, bulges and abrasions.
ii) The airline connector is in good
condition and that it connects securely to
the Pro-Pak pigtail.
iii) The air-supply conforms to EN 132
(see Section 1.3 - Compressed Air Airline
Supplies).
iv) The Pro-Pak airline coupling is in
good condition.
3.2 REPLACING SINGLE
CYLINDERS
1. Close the cylinder valve.
2 Open the facemask bypass to vent
the system.
3. Unscrew the cylinder connector.
4. Use the thumb of your right hand to
push the release tag away from the
clamp mechanism in the direction of the
arrow that appears on the moulded clamp
cover. The clamp mechanism will open,
allowing the cylinder to move freely within
the cylinder band.
