2 Description
2.1 Product overview
This variant of the Dräger PAS®Colt Series provides respiratory protection
for working in a contaminated environment using the air cylinder or an airline.
The equipment is available as a 10 minute or 15 minute short-duration
version. These are nominal durations available for self-contained use of
the equipment until a whistle sounds to warn the wearer that there is low
cylinder pressure. The nominal duration is determined by the capacity
(volume and pressure rating) of the selected air cylinder – the actual
duration is also dependent on the rate at which the wearer uses air from
the cylinder (the breathing rate).
The features of the equipment are:
●The carrying system is a bandolier shoulder harness and waist belt with
a hip mounted cylinder holster.
●The pressure reducer (Fig 1, Item 2) connects directly on to the air
cylinder, and reduces the cylinder pressure to the medium pressure
required at the lung demand valve (Fig 1, Item 1). The reducer has a
cylinder pressure gauge, and a whistle that sounds to warn the wearer
that there is low cylinder pressure.
●The airline connector (Fig 1, Item 4) is a male quick coupling that is
used to connect an independent air supply for airline use.
●The medium-pressure hose has a quick coupling that allows rapid
removal and fitting of the lung demand valve when required.
●The Dräger PAS®ASV (automatic switch-over valve), air cylinder and
lung demand valve are described below.
Optional feature:
●Dropdown cylinder holster: assists wearer movement by making the
cylinder and holster more manoeuvrable (in a confined space for
example).
2.1.1 PAS®ASV
The Dräger PAS®ASV (Fig 1, Item 3) allows the PAS®Colt to be used
with an independent air supply such as a factory airline or other breathing
air supply (e.g. Dräger PAS®AirPack). The switch-over valve
automatically switches between the airline supply and the PAS®Colt air
cylinder, maintaining an uninterrupted air supply to the wearer during
switching.
Refer to Fig 2
AL (airline) Input from an independent air supply
BA (breathing apparatus) Input from the PAS®Colt air cylinder
LDV (lung demand valve) Output to the lung demand valve
During airline use, the PAS®Colt is connected to a breathing-quality
independent air supply, and the PAS®Colt cylinder valve is open. The
PAS®ASV uses the independent air supply as the primary supply of
breathing air to the wearer, and the PAS®Colt air cylinder as the
secondary (or back-up) supply.
●If the independent air supply pressure remains above a preset switching
pressure the wearer breathes from the independent air supply.
●If the independent air supply pressure falls below the preset switching
pressure, the PAS®ASV automatically switches to supply the wearer
from the air cylinder, and the PAS®ASV whistle (Fig 2, Item 1) sounds.
If the independent air supply pressure recovers (increases above the
preset switching pressure), the PAS®ASV switches back to the
independent air supply and the whistle stops.
●If the independent air supply is disconnected, or falls to a very low
pressure, the PAS®ASV whistle stops.
See the technical data (Section 8) for the PAS®ASV operating pressures.
2.1.2 Air cylinder
Cylinders are available with a 200 bar or 300 bar working pressure rating,
and in steel or composite materials. Only air cylinders listed in the Dräger

certification are approved for use with the PAS®Colt. Contact Dräger for
further information.
2.1.3 Lung demand valve (LDV)
A variety of Dräger lung demand valves are compatible with this
equipment, with the coupling (Fig 3, Item 1) selected to match the face
mask coupling (see table below):
During use, the lung demand valve activates automatically as the wearer
breathes, and then regulates the breathing air supply into the face mask in
response to the breathing rate of the wearer.
●On positive-pressure systems, when the lung demand valve is
activated, the internal valve remains open until closed by the user.
Positive-pressure valves have a reset button (Fig 3, Item 2) that closes
the valve when required. Pressing the reset button closes the internal
valve to switch off the air flow through the lung demand valve.
●On negative-pressure systems the internal valve closes automatically
to switch off the air flow through the lung demand valve.
The lung demand valve can also be activated manually by pressing the front
button (Fig 3, Item 3) to open the internal valve and activate air flow when
required. During airline use only, the front button can be pressed to deliver
additional air (supplementary air) into the mask when required by the wearer.
2.2 Intended use
When this product is used with an approved face mask, air cylinder, lung
demand valve and independent air supply, it provides the wearer with
respiratory protection for working in contaminated or oxygen-deficient
conditions. It is intended for use in applications where a high level of
respiratory protection is required. The equipment is intended to be used for

i
3.2.1 Self-contained use (not supplied by an airline)
WARNING
The available duration starts from the time that the cylinder valve
is opened, and is dependent on the capacity of the cylinder and the
breathing rate of the wearer.
Dräger strongly advise that the front button (Fig 3, Item 3) is not
pressed to deliver supplementary air into the mask during self-
contained use. Using supplementary air would use air from the
cylinder and reduce the operating duration of the air supply.
●Regularly check the reading on the cylinder pressure gauge.
●If the whistle on the pressure reducer sounds, there is low cylinder
pressure. Immediately leave the hazardous area by the shortest and
safest route.
3.2.2 Airline use
WARNING
Dräger recommend that the user carries out a risk assessment to
establish local procedures to be followed in the event of failure of
the independent air supply.
If the PAS®ASV whistle sounds at any time during an operation,
the PAS®ASV has switched to supply the wearer from the PAS®
Colt air cylinder. If you continue to work while breathing from the
air cylinder, regularly check the cylinder pressure gauge – ensure
that the remaining air in the air cylinder allows sufficient time to
evacuate to a safe area.
During airline use, at very high work rates the pressure in the face
mask may become negative at peak inhalation flow.
NOTICE
The PAS®Colt cylinder valve must remain open during airline use.
●Connect the independent air supply to the male coupling (Fig 1,
Item 4), and if the independent air supply has a shut-off valve, open the
valve The PAS®ASV whistle will briefly sound to indicate that the
wearer is now breathing from the airline.
●If additional air is required, briefly press and release the front
button (Fig 3, Item 3) to deliver a single jet of supplementary air into
the mask.
●When the task is complete or when advised by a controller leave the
hazardous area:
○Disconnect from the independent air supply (see Section 3.2.1), or
○Remain connected and carefully withdraw the airline hose.
Evacuation procedure (independent air supply failure)
If the independent air supply fails, the wearer should proceed in line with
established local procedures (see warnings above).
●To evacuate proceed as follows:
a. Disconnect the independent air supply from the PAS®Colt.
b. Immediately leave the hazardous area by the shortest and safest
route.
When in a safe area, remove the lung demand valve from the face mask if
necessary and continue to breathe normally.
