1. Safety Regulations
1.1. Correct Use
UNIPACK II and UNIPACK II (2 nd Air) - referred to hereafter as compressed air
breathing apparatus - is a self-contained breathing apparatus operating
independent of the ambient air.
Breathable air is supplied to the user from a compressed air cylinder via a
pressure reducer, a demand controlled dosage assembly and a face piece. The
exhalation air is released directly into the ambient atmosphere.

The UNIPACK II models are compressed air breathing apparatus (CABA) for
work in contaminated hazardous environments.
The apparatus consists of the following main components:
• Carrying Assembly
• Pneumatic System
• Full Face Mask
• 6 or 7 L 200 bar or 6 L 300 bar Steel or Composite Cylinder or 6,8 L 300
bar Composite Cylinder
The UNIPACK II BA (Fig. 1) and UNIPACK II (2 nd air) with supplementary air
supply (Fig. 2) are part of MSA’s Modular Breathing Apparatus System
comprising of several different models to meet different users’ requirements. The
Order No.: 10093180/00 Page 6 of 30

apparatus uses a single compressed air cylinder for the air storage. The cylinder
is mounted onto an ergonomic designed back plate.
The high pressure in the cylinder is reduced in two steps or stages, down to a
pressure which can be called breathable air. This type of equipment is known as
a two-stage apparatus. This is done to achieve lowest possible resistance and
high capacity when breathing in the unit i.e. very low breathing exertion even at
very high workloads.
The first reduction of the high pressure is performed in the pressure regulator
where the pressure is reduced down to a medium pressure of approx. 7 bar. The
pressure regulator is a balanced piston type pressure reducer.
The second reduction from 7 bar down to normal air is performed by the
breathing valve located at the face mask. This breathing valve is a demand valve
which means that it senses the demand for an inhalation of air and it opens to
permit exactly the air flow demanded. The inlet valve closes when the inhalation
stops and a spring loaded exhalation valve in the mask opens upon exhalation.
The spring loaded exhalation valve creates a small positive pressure inside the
mask during the whole breathing cycle to effectively prevent any inward leakage
from surrounding atmosphere. This function starts automatically by the first breath
and is known as first breath positive pressure activation.
The apparatus has an audible warning device placed at the 1st stage pressure
reducer.
2.1. Carrying Assembly
The carrying assembly consists of an ergonomic designed back plate of heat
resistant glass fibre reinforced polyamid material with carrying slots for easy
transport of the apparatus.
The harness is of self-extinguishing polyester fabric and can be quickly replaced.
On the lower part of the carrying assembly is the support for the pressure
reducer. On the upper part of the carrying plate is an integrated cylinder support
which with an adjustable cylinder retaining strap and a tension lever permits
connecting various compressed air cylinders.
The back plate is equipped with a 125 kHz transponder (RFID chip) next to the
label for easy identification.

3 Warning signal
4 High pressure line
5 Medium pressure line
The pressure reducer is mounted in the lower area of the back plate ( Fig. 1
and Fig. 2).
On the pressure reducer, there is a safety valve and the single line for connecting
the manifold. The pressure reducer reduces the cylinder pressure to
approx. 7 bar and the safety valve activates on non-permitted pressure rise to
prevent damage insuring the continued supply of breathable air.
The warning device is set to give off an audible signal when the cylinder pressure
is reduced to approx. 55 bar. It continues to sound continuously, medium
pressure dosed until the usable air supply is nearly exhausted.
The individual high pressure and medium pressure lines are routed separately
from the pressure reducer to the individual end units or connections.
The pressure gauge ( Fig. 4) is fitted at the end of the high-pressure line.

2.2.2. Lung Governed Demand Valve
The positive pressure lung governed demand valve AutoMaXX AS is fixed at the
end of the medium pressure line. The connection to the full face mask is by
means of a plug connector. This assures safe and easy handling. The freely
pivoting plug connector automatically adapts itself to the head movements of the
user. ( Fig. 5)

3 Medium pressure line
The Second Medium Pressure Line is an additional feature on the UNIPACK II
(2 nd Air) Breathing Apparatus.
There is a second medium pressure connection with safety coupling on the hip
belt, which is closed off with a plug when not being used.
In consideration of national regulations, you can use this connection to:
connect a second lung governed demand valve;
a rescue set, consisting of a normal pressure lung governed demand
valve and full face mask for rescuing people;
connect to compressed air line system using the double, e.g. for
decontamination after use or
to connect a rescue hood.
Warning!
When rescuing persons with the rescue set via the second connection,
more air is consumed.
Hence, the service time is considerably reduced. Always keep this in
mind when using your apparatus.
Order No.: 10093180/00 Page 10 of 30

2.3. Full face mask
The 3-S-PS-MaXX Mask is not a complete respiratory protective device by itself,
but a part which connects the device with the respiratory tracts of the user
(facepiece). It serves as facepiece (EN 136, class 3 and EN 136-10) with plug-in
connector for positive pressure (pressure demand) compressed air breathing
apparatus and can only be used with the corresponding compressed air breathing
apparatus UNIPACK II (Fig. 7).
Fig. 7 3S-PS-MaXX Mask
The rubber head harness has five straps that are tightened and locked by
buckles. The wide sealing edge of the mask is pressed slightly against the face
by positive pressure and follows the contours of the face giving an effective seal.
The inhalation air flows from the connector of the mask past the inhalation valve
to the inside of the lens (thus keeping the lens largely fog-free) and then through
the check valves into the nose cup.
The dead space has been minimized by the inner mask and separate inhalation
and exhalation channels which coincide with channels in the breathing valve.
The exhalation air passes through the exhalation valve directly to the ambient
atmosphere.
In that way, inhalation and exhalation air will never be mixed
Order No.: 10093180/00 Page 11 of 30

2.4. Compressed Air Cylinders
The MSA/UNITOR cylinder is type-tested and approved for the respective
operating pressures.
The air inside the cylinders must be according to EN 12021.Depending on the
temperature and humidity of the ambient atmosphere, icing may form on the
cylinder valve, pressure reducer and coupling; this, however, does not influence
the function of the apparatus. Compressed air cylinders must be ordered
separately.
Order No.: 10093180/00 Page 12 of 30
