    Scrubber volume reducer

    Is possible for you to buy or build this kind of device?
    DRAGER Dolphin Rebreather 1/2 Fill Canister Adaptor su eBay.it SCUBA Snorkeling, Water Sports, Sporting Goods
    Does the half scrub will last the half of time?
    May be someone did forget the reaction zone, isn't it?

    has been debated, don't use this!

    the only place you could use it, is a pool, minimum 25°, sofnolime

    (so warm, and not deep)

    and then short duration, but how long?? half a scrubber has far less then half the original duration

    I see no use for it at all, simply stock your scrubber well closed between the dives

    ...."Yes you have to pre-breathe to activate the scrubber sorb, anyone who says different doesn't know what they are talking about!"...
    .... to get more accurate CO2 injection in the breathing machine we put 2 mass flow controllers in series ...
    .... The noise is a few tens of nano-volts, so DL were able to reduce the output voltage ...
    .... radial scrubbers give longer dwell time than axials...
    .... the earth is flat and ...

    The normal use of a full dolphin scrubber is more than 3 hours. With the half fill, the duration drop to less than a third of it.

    Fine! So its'exactly what I was meaning.
    The metter is that you need Draeger tests to know the authonomy.
    How much less than one third?
    That's the question!

    If Draeger has tested the scrubber's authonomy with this device the risk is low if well done, but generally people do this devices on scrubber that are not tested in suchconditions.
    What Draeger say about their volume reducer? What's the authonomy related to the tests?

    Tests are very important because canister efficiency varies also with the diameter to lenght ratio.

    During the course, normally the intructor explain also this part of the use of the Draeger. At least the instructor who certified me.

    I have it, i used it with a maximum time of 60', as stated during my courses, and i still don't get what is the matter in selling it: it is a Draeger spare part.
