Dräger Quaestor 5000/7000
Description
The following accessories are included with the Dräger
Quaestor 7000:
External microphone
The microphone registers the signal of the acoustic whistle
when inspecting a compressed air breathing apparatus or
rebreathing apparatus.
Bracket for gauge or Bodyguard
The bracket is available as an option for the Dräger
Quaestor 5000.
The following accessories are available as options both for the
Dräger Quaestor 5000 and for the Dräger Quaestor 7000:
200 bar-Option
If the test device is to be operated at a test pressure of
200 bar, the 200 bar option must be connected. In addition,
it is only permitted for there to be a pressure of 200 bar on
the high pressure inlet. Dräger recommends connecting
pressure reducer R 57 584 to the high pressure inlet.
If the pressure in the test device is higher than 200 bar,
the air is released without damaging the respiratory
protective device.
Compressed air breathing apparatus bracket
for the upright positioning of the apparatus during the test
Adapter for mask/helmet combinations
for mounting the mask onto the test head without head
harness
QSI

-Box
for sound isolation of the residual pressure warning from
gauge or Bodyguard
Breathing adapter
for positive leak test conforming to vfdb 0804
Hood
to protect the test device against dust and water
2.3
Intended use
The basic version of the Dräger Quaestor 5000/7000 can be
used to test compressed air breathing apparatus, compressed
air hose breathing respirators and full face masks. Depending
on the device version, the tests can be performed on the
following components:
Full face mask:
Positive pressure leak test
Negative pressure leak test
Opening pressure of the exhalation valve
Head-up display test (manual)
2
On the lung demand valve:
Positive pressure leak test
Negative pressure leak test
Opening pressure
Switching pressure
Static positive pressure
Metering valve test
Breathing test (test of the dynamic breathing resistance)
On the compressed air breathing apparatus
Static medium pressure
Increase in the medium pressure
High pressure leak test
Comparative test for pressure gauge
Head-up display test (manual)
2
Response pressure of the acoustic warning device
Breathing test (test of the dynamic breathing
resistance)
On the chemical protection suit
Leak tightness of the chemical protection suit
Leak tightness of suit valves
Chemical protection suits can be tested in a fully automated
way using the Dräger Quaestor 7000. The Dräger
Quaestor 5000 can be used to perform the measurements via
the measuring point in the eye, however the protection suit
must be inflated using a compressed air gun.
Both test devices can be expanded using modules that can be
used to test closed-circuit breathing apparatus and the safety
valve on pressure reducers. The Dräger Quaestor 7000 can
also have a module added that can be used to test diving
apparatus.
The tests are conducted in accordance with the VFDB
Directive 0804 and for the compressed air breathing apparatus
also in accordance with EN 137.
