Liability Statement
Terms and Conditions of warranty for the Dräger PAS AirPack 1 Trolley Module can be obtained from Dräger
on request. Responsibility for reliable function of the equipment transfers to the owner or operator when
serviced or repaired by untrained personnel, (not employed or authorised by Dräger), or when used in a manner
not conforming to its intended use.
Description and Intended Use
The Dräger PAS AirPack 1 Trolley Module is a
compact mobile two-wheel trolley unit with
flexible rubber airline hose and hose winding drum,
plus storage capacity for two valved high-pressure
cylinder assemblies. The module provides a low-
pressure independent breathing air supply to the
wearer of approved Dräger breathing apparatus
fitted with airline manifold connections.
The equipment is compatible with a range of
associated breathing apparatus and
accessories and must be used only with air that
complies with the air quality requirements of
respirable breathable air at the pressure and
quantities (volumes) required. When the airline
fitting of the breathing apparatus is connected
to the module, the approved configuration
provides the wearer with respiratory protection
when working in a contaminated or oxygen
deficient gaseous atmosphere.
The manifold assembly of the module allows for
the repeated removal and fitting of cylinders,
transferring of air supply from one cylinder to
another. This feature provides a means of
providing an uninterrupted air supply to the
wearer.
Automatic activation of a preset mechanical high
pressure whistle warning unit (HPWWU) alerts
the Controller of low cylinder pressure. Activation
of a low pressure whistle warning unit (LPWWU)
alerts the Controller of a drop in pressure of the
low-pressure air supply.
If required, the cylinders may be bypassed by
connecting the inlet coupling of the trolley
module to an independent low-pressure air
supply, e.g. from a works airline or LP
compressor (refer to Main Airline Pressures and
Flow and Air Quality requirement . A drop in
low air supply pressure is highlighted to the
Controller by the activation of an audible low
pressure whistle warning unit (LPWWU).
The possible available extended working duration,
depends on the configuration selected (attached to
works airline or LP compressor - with filter unit to
maintain air quality), the capacity (volume) of
cylinder(s) selected, the number of fully charged
cylinders available and the breathing rate of the
wearer(s).
Important Note: No more than two users of
approved airline breathing equipment
should be connected to the AirPack 1
Trolley Module at any time, and in any
configuration. Refer to the Equipment
Configuration details chart.
Details of equipment variants, associated
breathing equipment and accessories are
available from Dräger on request.
