Hi everyone, I am new to Rebreather World.

The idea of a ventilator in combination with a rebreather has come up before, in discussions about very deep dives where WOB becomes a limit for the diver. A system build for such purpose would have to have the same redundancies as the rebreather itself in order to be safe.

Matt, just some food for thought. I don't know what depth range you're targeting, but if you're looking at shallow dive applications (to 6 meters/20 feet) an O2 rebreather is a smaller, lighter and most of all simpler solution. While any Rebreather can be used with pure O2 in shallow water (Dräger even sells a "pool jet" for the Dolphin SCR), any mixed gas CCR is a more complicated design.

The Evolution you like has tripple sensors, dual conrtollers, dual displays, dual batteries, all stuff you won't really need for shallow water application. The simpler the unit, the less likely it is to fail.

Many O2 rebreathers are chest mounted rather than dorsal designs. That means you could have the ventilator designed into a backpack. What size, weight (for balance UW) and power requirements does the ventilator have?

Thank you for the great thoughts on the rebreather. Our goal is 20 to 30 feet. That is a good number all the way around since I am diving in Key Largo. The ventilator can handle 33 feet and it weighs 12#. The internal battery last for nine and half hours and totally sealed. We will have a back up battery to. We will need to make a water tight housing for the vent. In the water tight housing we would put controls like a camera housing has to be able to change setting if needed on the vent. If you want to know more about the vent just ask me and I will e-mail the manual.

I agree, we don't need the hi-tech rebreather, just keep it simple since I am only going 20 to 30 feet. I think the OMG C-96 PRO Rebreather.

This is defiantly do able with a vent and rebreather. Like anything else one needs the right people, lots of research and testing and of course money and any thing is possible.

Talk to you later Matt.
