Isnt the IP deturmined by the 02 usage rate of the diver?
Has it got a fixed oraface or does it have a needle valve?
If its a fixed oraface like the KISS then you will need at least 11 bar to go to 100m. Beyound that you will need to alter the oraface size and customise the first stage spring to give a much higher IP
I am reasnobly certain the CE mark has absolutly nothing to do with its abuility to go to X depth, so id ignore that issue.

having read the numérous rebreather worls posts about this rebreather certification I would not trust the 100 m certification...
many people say it only have a fake certification for mine use
