Why did you post each picture three times?
Someone's gotta clear up that space and the staff isn't bored ...
I realize they aren't your images, and they look pretty cool but they don't quite serve their purpose if they're supposed to show us something. Least of all the Carmelion replacement scrubber.

Flat black product on a black backdrop isn't easy to light properly. And lighting from the top when said scrubber is on the bottom ain't the way to go.
That Carmelion thing looks pretty good, certainly very cool, and having seen Michael's excellent craftsmanship I'm looking forward to see the real thing. But may I suggest calling it something other than a replacement scrubber?
For one thing, it's much more than that. I consider a Cis can in a Meg or a Micropore can in a Dolphin a replacement scrubber. This is a replacement everything but the front part of the loop and the gas supply.
Second, the one thing not shown or detailed is the scrubber.

The most interesting part, one of hardest parts of a rebreather to design well, and one of the most important part regarding its performance and safety.
So what exactly are you replacing the AP scrubber(s) with?
