Instructions for use

Dräger BG ProAir

Maintenance 

The hand wheel for the compressed oxygen cylinder 

must be positioned in the depression on the outside of the 

carrying frame.

4. Tighten the hand wheel of the pressure reducer to the 

compressed oxygen cylinder. Do not use any tools to 

tighten.

5. Thread the cylinder strap into the buckle and close the 

hook-and-loop fastener. Slide the buckle onto the edge of 

the breathing bag so that the lid of the closed-circuit 

breathing apparatus can be closed.

5.2.5.9 Closing the closed-circuit breathing apparatus

1. Interlink the hinges and lock them in place.
2. Close the lid and engage the locking mechanisms. A click 

can be heard.

5.2.5.10 Fitting the waist belt and shoulder straps

1. Fit the top ends of the shoulder straps. To do so, insert the 

connecting elements in the mounts on the carrying frame 

and engage. The loops should point towards one another.

2. Fit the bottom ends of the shoulder straps. To do so, insert 

the connecting elements in the mounts on the carrying 

frame and engage.

3. Fit the waist belt. To do so, position the waist belt plate 

with the recess facing upwards on the carrying frame’s 

waist belt support and secure with the split pin.

4. Fasten the Connect ECU on the shoulder strap.

5.2.6  Testing the closed-circuit breathing 

apparatus

5.2.6.1  Notes for testing

The following test sequence applies for both apparatuses with 

constant oxygen dosage and those with on-demand oxygen 

dosage. The pre-flush unit does not need to be tested for 

apparatuses with constant oxygen dosage. This test is 

marked accordingly.

Carry out a visual inspection, as well as a leak and functional 

test, after every service. If a fault is detected during the leak 

and functional test, the closed-circuit breathing apparatus 

must not be used. Appoint qualified personnel to service the 

apparatus or send it to Dräger.

If the CO

2

 absorber is installed in the closed-circuit breathing 

apparatus, the leak and functional test can be performed a 

total of six times, whereby testing should not take longer than 

15 minutes. After these 6 tests, the CO

2

 absorber must be 

replaced and must no longer be used.

The tests are described using the Dräger RZ 7000 by way 

of example. The sequence of the tests described in these 

instructions for use is the optimum sequence with this test 

unit. The closed-circuit breathing apparatus can also be 

tested with other suitable test units in other sequences.

The tests should not be performed in direct sunlight or in a 

cold room as the air pressure in the device will then change 

quickly and can result in incorrect test results.
