Liability Statement
Terms and Conditions of warranty for the Drä er PAS AirPack 1 Trolley Module can be obtained from Drä er
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 Drä er), or when used in a manner
not conformin to its intended use.
Description and Intended Use
The Drä er PAS AirPack 1 Trolley Module is a
compact mobile two-wheel trolley unit with
flexible rubber airline hose and hose windin drum,
plus stora e capacity for two valved hi h-pressure
cylinder assemblies. The module provides a low-
pressure independent breathin air supply to the
wearer of approved Drä er breathin apparatus
fitted with airline manifold connections.
The equipment is compatible with a ran e of
associated breathin 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
fittin of the breathin apparatus is connected
to the module, the approved confi uration
provides the wearer with respiratory protection
when workin in a contaminated or oxy en
deficient aseous atmosphere.
The manifold assembly of the module allows for
the repeated removal and fittin of cylinders,
transferrin of air supply from one cylinder to
another. This feature provides a means of
providin an uninterrupted air supply to the
wearer.
Automatic activation of a preset mechanical hi h
pressure whistle warnin unit (HPWWU) alerts
the Controller of low cylinder pressure. Activation
of a low pressure whistle warnin unit (LPWWU)
alerts the Controller of a drop in pressure of the
low-pressure air supply.
If required, the cylinders may be bypassed by
connectin the inlet couplin of the trolley
module to an independent low-pressure air
supply, e. . 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 hi hli hted to the
Controller by the activation of an audible low
pressure whistle warnin unit (LPWWU).
The possible available extended workin duration,
depends on the confi uration 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 char ed
cylinders available and the breathin rate of the
wearer(s).
Important Note: No more than two users of
approved airline breathin equipment
should be connected to the AirPack 1
Trolley Module at any time, and in any
confi uration. Refer to the Equipment
Confi uration details chart.
Details of equipment variants, associated
breathin equipment and accessories are
available from Drä er on request.
