Strictly follow the Instructions for Use
Any use of the breathing air tester requires full understanding and
strict observation of these instructions.
The breathing air tester is only to be used for the purposes specified
here.
Maintenance
The breathing air tester must be inspected and serviced by experts at
regular intervals and a record kept. Repair and general overhaul of
the breathing air tester may only be carried out by trained service

Description / Intended Use
The Dräger Aerotest Alpha determines the quality of the breathing air
delivered by a low pressure system (compressor, compressed air
cylinder or compressed air network). The maximum supply pressure
at the device inlets is 15 bar. Dräger tubes
measurements.
The levels of the following substances can be measured:
— Oil
— Carbon dioxide (CO
— Carbon monoxide (CO) and
— Water vapour (H
These four values can be defined either simultaneously or individually.
)

O).

The measurement precision remains constant regardless how many
tube holders are loaded. By contrast, the assigned functions of the
Dräger tubes
®
/ tube holders must be taken into account. In other
words, in order to check e.g. the oil content of the breathing air, the
oil tube must be loaded in the appropriate holder marked “oil“.
The permissible limit values are defined in EN 12 021 (Compressed
air for breathing apparatus).
Measuring Unit: Pos. 9
The measuring unit needs a supply pressure of 3 bar.
Pressure Control Valve: Pos. 8
The pressure control valve is preset to 3 bar of relief pressure.
When the supply pressure changes from 3 to 15 bar, the relief pressure (3 bar) at the handwheel of the pressure control valve must be
readjusted. Check via the pressure gauge.

All the components required for measurement are housed in a handy
carrying case.

Preparation
p
● Clean the compressed air supply connection by blowing it clear.
● Clean the measuring unit. It must be free of particles and dust.
● Check pass-through of the measuring unit (see page 23).
1 Connect the measuring unit to the compressed air supply
connection. The maximum supply pressure is 15 bar. If necessary,
use the adapter.
Outlet pressure 3 bar adjustable at the pressure-reducing valve
with pressure gauge.
● Slowly open the compressed air supply valve and flush the system
(allow compressed air to be exhausted through the system).
Flushing time for a regularly maintained system:
2 to 3 minutes.
For other systems:
5 to 6 minutes.
● Then close the valve.
● Set the timer: 5 minutes.
Strictly follow the specific Instructions for Use.
