2 Description
2.1 Product overview
This variant of the Dräger PAS Colt Series provides respiratory protection
for escaping from a contaminated environment using breathing air from the
air cylinder.
The equipment is available as a 10 minute, 15 minute or 20 minute
version. These are the nominal escape durations, which are determined by
the capacity (volume and pressure rating) of the air cylinder selected. The
actual escape 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 Dräger air cylinder and lung demand valve are described below.
Optional features:
● Dropdown cylinder holster: assists wearer movement by making the
cylinder and holster more manoeuvrable (in a confined space for
example).
● ChargAir

direct filling system: see the ChargAir
TM
Instructions for Use
for a description and operating instructions.
2.1.1 Air cylinder
Cylinders are available with a 200 bar or 300 bar working pressure rating,
and in steel, aluminium or composite materials. The pressure in the air
cylinder is shown on a contents indicator on the cylinder. Only air cylinders
listed in the Dräger certification are approved for use with the PAS Colt.
Contact Dräger for further information.
2.1.2 Lung demand valve (LDV)
A variety of Dräger lung demand valves are compatible with this
equipment, with the coupling (Fig 2, 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 2, 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.
2.2 Intended use
When this product is used with an approved face mask, air cylinder and
lung demand valve, it provides the wearer with respiratory protection for
escaping from 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 only for escape
applications.

Notes
Dräger recommendations
1. These maintenance tasks may only be carried out by Dräger or trained
service personnel. Details of the tests are contained in the Technical
Manual which is issued to service personnel that have attended a
relevant Dräger maintenance course.
2. Lightly lubricate the O-ring of the lung demand valve (A-type coupling
only) as required (recommended lubricant is Dow Corning
Molykote 111 Valve Lubricant and Sealant). Products other than the
recommended lubricant are not tested and may damage the
equipment.
3. Replace the sintered filter if a drop in reducer performance is observed
during a flow check or if it is visibly damaged.
4. Replace the high-pressure connector O-ring if it is found to leak during
functional testing or if the O-ring is visibly damaged.
5. Where the breathing apparatus is subjected to a high level of use (in
training establishments etc.), reduce the overhaul period for the
pressure reducer. In these circumstances, Dräger recommend that the
overhaul frequency should be less than 5,000 applications of use. An
application of use is defined as a single use of the fully assembled
breathing apparatus, where the user breathes from the air cylinder. It
does not include system pressurization for pre-operational checks.
5.2 Maintenance tasks
5.2.1 Removing the cylinder
WARNING
