    I believe the Dolphin set up is similar to the Atty, if there is a difference feel free to ignore me.

    By pool jet do you mean the 100% O2 jet? You wouldn't fit it to the bypass but replace one of the dose jets. The flow rate is 1.6 L/min IIRC, the TecMe page may have a bit more info.

    Hi David
    Thanks for reply , were did you get information from ?
    With the Atlantis i was also concerned about the material the lungs are made of.
    Any idea how i test flow rate of the pool jet / 100% dose jet .
    Would like to turn the 1.6ltr down.. 1tr would be nice maybe even .8 .
    What do you think ?
    Cheers

    The flow rate is set the same as the others [in the factory with a ruby and a laser] and is non adjustable.

    Hi.
    Just take another fixed pressure first stage with an IP matched to meet your target. CMF should vary linearly with drive pressure.

    If you're using pure O2 then couldn't you just blank off the connection to the orifice and run it off the bypass? Loss of lung volume would trip the ADV and keep the loop topped up.

    Re: Pool jet installation

    If you would like a lower flowrate, lower the IP of your Atlantis first stage to the desired flow. Your ADV will work, though it will be somewhat harder to trigger.
    That way you will still keep the built in IP creep should the jet be blocked by accident.
    As Stewart suggests use the ADV only. But as i understand you, the intention is to use the Atlantis for pure o2 only ? In that case you have no other use for the Atlantis first stage anyway.

    If you use a Dolphin inhale lung you can add an oxygauge. Seems you have both, as i do :)

    What are your concerns regarding the Counterlungs. I always liked the fact that i can see if they are clean or not, but they are not as easily repaired as the Dolphin CLs. And the heavy fittings tend to punch holes in them when dropped

    Best regards
