4 Description and Intended Use
The Dräger PAS Colt Series of Bandolier Airline/Escape equipment
consists of:
● Bandolier Shoulder Harness with Waist Belt.
● Pressure Reducer with integral Lung Demand Valve (LDV).
● Hip Mounted Cylinder Carrying Holster.
● Airline Manifold Connection – with or without low pressure whistle
warning unit (LPWWU).
● Valved Cylinder Assembly with Contents Indicator.
The equipment is available in either 10 minute, 15 minute or 20 minute
nominal escape duration versions.
4.1 Optional Variants
● Pressure Reducer with ChargAir – Direct Filling Assembly.
● Cylinder Carrying Holster – Drop Down. If applicable, refer to
additional enclosed Instructions for Use.
Important Note: When using equipment fitted with a ChargAir
connection it is necessary to refer to the Use of ChargAir – Direct
Filling instructions supplied with the equipment.
4.2 Accessories
● Thigh strap
This series of equipment utilises a high performance first stage pressure
reducer in association with an integral lung demand valve. The equipment
is compatible with a range of face mask and compressed air cylinders.
When used in approved carrying system, valved cylinder assembly, LDV
and face mask combinations, the equipment provides the wearer with
respiratory protection when working in, or escaping from a contaminated
or oxygen deficient gaseous atmosphere.
When the airline manifold coupling of the equipment is connected to a
low-pressure independent air supply of breathable air quality, (e.g. Dräger
AirPack System or filtered works airline), then the equipment functions as an
airline working set. In this configuration the cylinder valve of the equipment is
in the closed position. On failure or interruption of the independent air supply
the wearer opens the cylinder valve, disconnects the independent air supply
from the airline manifold connection and then proceeds to escape to a safe
area using the available air supplied from the cylinder.
During escape, the effective duration of the equipment is dependant on the
capacity (volume) of the cylinder selected and the breathing rate of the
wearer.
Safety Warning: When the equipment is worn as an airline working
set then the escape duration starts from the time of opening the
cylinder valve and disconnecting the airline supply. The time
required to allow the wearer to escape to a safe area must be within
the capacity (volume) of the cylinder selected taking into account the
breathing rate of the wearer. When selecting the type and duration of
escape equipment it is essential to consider the potential hazards,
and probable escape routes.
Details of the equipment variants, accessories, and any approved
independent air supply source configurations are available from Dräger on
request.
5 Technical Data

● Push-In Type A – Positive Pressure (PP).
● Screw-In Type AE – Positive Pressure (PP).
● Screw-In Type N – Normal Demand (ND).
Refer to the Instructions for Use supplied with the face mask.
5.3 Compressed Air Cylinders
Cylinders are available in either steel, aluminium or composite materials.
Contact Dräger for details.
Cylinders supplied by Dräger are charged at an ambient temperature of
15 °C and to the nominal cylinder pressure – i.e. contents indicator needle
must be aligned with the nominal charged pressure – 200 or 300bar.
5.4 Airline Manifold Connection
A Male Coupling is incorporated on the airline manifold for the connection
of a quick release coupling (QRC) from an independent air supply.
Instructions for Use
5.5 Airline Operating Pressures and Flow
The selected low pressure independent air supply must meet the following
parameters.
● One User – 6bar to 10bar – airflow rate of at least 550 Litres/minute.
● Two Users – 7bar to 10bar – airflow rate of at least 550 Litres/minute.
When using an Airline Manifold Connection – with LPWWU, the whistle
activation pressure is preset by Dräger to between 5bar – 4bar.
Safety Warning: Air quality for compressed air breathing systems
must conform to the requirements of EN12021. Do Not use oxygen or
oxygen enriched air.
6 Preparation for Use
A trained and competent person must perform the following checks and
preparation procedures before release of the equipment to a potential
wearer for operational use.
6.1 Visual Inspection
Check the integrity of,
● Bandolier Shoulder Harness with Waist Belt.
● Cylinder Carrying Holster.
● Pressure Reducer, LDV and Hose Assemblies.
● Airline Manifold Connection and Hose – with or without LPWWU.
● Face mask – refer to the relevant Instructions for Use.
● Valved Cylinder Assembly with Contents Indicator.
Optional Variants
● Cylinder Carrying Holster – Drop Down. Check function of the latching
mechanism.
6.2 Fitting Cylinder
2
● Check the contents indicator ensuring the cylinder is fully charged, i.e.
1588/1591 contents indicator needle must be aligned with the nominal charged
pressure – 200 or 300 bar.
3
● Check that the threads of the valve port and the reducer hand wheel
are undamaged, connector O-ring is in position, and undamaged. Fully
2
insert the fully charged cylinder into the carrying Holster.
Caution: To prevent damage, ensure that the hand wheel of the
pressure reducer remains clear of the cylinder.
1
● Screw the hand wheel of the pressure reducer (clockwise) to the port
of the cylinder valve and tighten the hand wheel – handtight.
Important Note: The following test will verify the integrity of the
1597
complete assembly. The pressure leak test described should also be
carried out following the reassembly of any of the component parts
2 4 6 of the pneumatic assembly (spares etc).
6.3 Pressure Leak Test
● Again check the contents indicator ensuring the cylinder is fully
charged, i.e. contents indicator needle must be aligned with the
nominal charged pressure – 200 or 300bar.
● Type A and AE – Press the reset button of the LDV to switch 'Off'
positive pressure.
3 5
● 'Open' the cylinder valve slowly, but fully, to pressurise the system
then 'Close' the valve.
0584
Test Parameters – Check for no audible leak. If necessary, use soap and
water based solution to locate a suspected leak.
Passed Test – Fold the rubber cover from the front of lung demand valve
and press centre of diaphragm to vent pressure from rubber hose and
reducer. Refit the rubber cover.
Type A and AE – Press the reset button of the LDV to switch 'Off' positive
pressure.
Failed Test – Fold the rubber cover from the front of lung demand valve
and press centre of diaphragm to vent pressure from rubber hose and
4961
reducer. Refit the rubber cover. Investigate the source of the leak, rectify
and repeat the test. Until the leak is rectified Do Not release the equipment
for use.
6.4 Leak Test and LP Flow Test – Airline Connection
Refer to Technical Data.
Important Note: If using a works airline to perform the following tests,
then connect the isolation valve (3353449) to the female coupling of
the airline outlet.
● Connect the male coupling (1) Fig. 2 to the female quick release
coupling (QRC) of the independent air supply.
● Type A and AE – Press the reset button of the LDV to switch 'Off'
positive pressure.
● 'Open' the valve of the independent air supply to pressurise the
2
system.
Test Parameter – Check for no audible leak.
● Open' the cylinder valve of the breathing equipment to pressurise the
system, then disconnect the male coupling (1) Fig. 2 from the female
QRC of the hose from the independent air supply.
Test Parameter – Non-return valve check – Check for no audible leak from
3903
the female QRC.
● 'Close' the cylinder valve of the breathing equipment, then reconnect
the male coupling (1) Fig. 2 to the female QRC of the independent air
supply.
● Fold the rubber cover from the front of lung demand valve and press
centre of diaphragm to activate the airflow from the LDV. Refit the
rubber cover. See Safety Warning.
Safety Warning: Do Not direct the airflow onto the face, eyes or skin.
Test Parameters – An unobstructed airflow should vent from the outlet of
the LDV. This test should take a minimum of 3 to 5 seconds.
● 'Close' the valve of the independent air supply and observe the low
pressure LP gauge, or the high pressure (HP) gauge, if fitted.
Test Parameters
LP Gauge – Indicated pressure should not decrease more than 1bar in
1 minute.
