EBME Forums Forums Maintenance Service Manuals & Schematics drager savina 300 service manual

Hi MikeSzym

What specific test are you doing? I'm interested in this.

The following section of IFU, but I wanted to confirm the Drager setup they use:

Check safety features:
– Correct functioning of the emergency expiratory valve: Pressure rise 1.9 to 4.4 mbar (1.9 to 4.4 cmH2O) at a flow of 4.5 to 5.5 L/min.
– Correct functioning of the non-return valve in the expiratory valve.
– Correct functioning of the emergency breathing valve: Maximum pressure drop of 4 mbar (4 cmH2O) at a suction flow of 60 to 65 L/min.
– Correct functioning of the non-return valves in the gas inlet for O2 and Air

Usually, as I recall, during the power-on self-test, the test items you described can be completed.

If you are particularly concerned about the accuracy of the flow rate, you need an gasflow analyzer to accurately test

Looking forward to your test results

Thanks mate,

But those particular tests require a more nuanced setup ... i.e. injectors and creation of certain suction levels.

Don't you have a dedicated gasflow analyzer? For example, Fluke VT650?VT PLUS HF?Timeter RT-200?T300.....
