2 Description
2.1 Product overview
The Dräger PAS ® Series of airline respiratory protection equipment
provides respiratory protection for working in a contaminated environment
using an airline.
The features of the equipment are:
● There are two harness types available: a bandolier harness (Fig 1) that
has a waist belt and a shoulder strap, or waist belt only harness (Fig 2).
● The airline connector (Fig 1, Item 4) is a male quick coupling that is
used to connect an independent air supply.
● The equipment is available with or without a low-pressure whistle.
When the equipment has a low-pressure whistle, it is on the airline
manifold (Fig 1, Item 2), and sounds during use to warn the wearer that
the supply pressure from the airline is low.
● The medium-pressure hose is available with or without a quick
coupling (Fig 1, Item 3) (shown on the bandolier harness only). The
quick coupling allows rapid removal and fitting of the lung demand
valve when required.
● The lung demand valve (Fig 1, Item 1) is described below.
2.1.1 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):
LDV Face Type Coupling type
coupling mask
coupling
A P Positive Push-in – Dräger specific
pressure
AE PE Positive Screw-in – M45 x 3 to
pressure EN 148-3
N RA Negative Screw-in – 40 mm round
pressure thread to EN 148-1
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. The front button can be pressed during use 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, 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 only for airline
applications.
The face mask (full face mask conforming to EN 136 Class 2 or Class 3)
and other accessories used with this product must be certified Dräger
components, assembled in an approved configuration; otherwise the
operation of the device may be impaired. Contact Dräger for further
information.

flammability may be a risk. Marking on the compressed-air supply tube
indicates that the tube is heat resistant (H) and/or antistatic (S).
3 Use
WARNING
The airline air quality shall meet the requirements for breathing air
according to EN 12021. Do not use oxygen or oxygen-enriched air.
The moisture content of breathing air should be controlled within
the EN 12021 limits to avoid freezing the apparatus.
Carry out a risk assessment of the workplace to ensure that it is
not possible to connect to any airline supply other than breathable
air (e.g. Nitrox).
Before using airline equipment, ensure that the independent air
supply meets the air quality requirements, and complies with the
airline pressure, flow and hose requirements in the technical
data (see Section 8), and has been issued with a permit for use if
necessary.
Position the source of the independent air supply in a safe and
uncontaminated area. Dräger recommend that a controller should
monitor and maintain the independent air supply throughout any
operation.
3.1 Preparation for use
3.1.1 Visual inspection
Carry out a visual inspection, checking the full breathing apparatus
including all component parts and accessories. Check that the equipment
is clean and undamaged, paying particular attention to pneumatic
components, hoses and connectors. Typical signs of damage that may
affect the operation of the breathing apparatus include impact, abrasion,
cutting, corrosion and discoloration. Report damage to service personnel
and do not use the apparatus until faults are rectified.
Instructions for Use
3.1.2 Functional testing
WARNING
If the breathing apparatus fails to meet any of the standards or
parameters described in the functional tests, or if an immediate
