That's your opinion, of course...

When Jakub (or someone else) is ready to make one, it could be made easily with in-out flow or reverse.

What are the minor mods?
If it is not something major then it can probably be done even now.

ps: the radials for the rEvo are finished.... in powershape :-)

I really liked the radial scubber Skipbreather made and posted in the Rebreather World library (which is close in design to the CisLunar) so I did some number crunching myself. First created drawings in eMachineshop (thanks for the recommendation Dave S.) and then got price quotes on the major components of the scrubber. Here they are:

Attachment 7361

So *if* there were enough people interested and *if* they were willing to do the final assembly themselves the parts could be ordered at a significant savings.

This appears to be a community no-brainer... Qty 25, w/ the custom parts coming in just over $100... Heck, even add a few bucks for coordination/packaging/shipping and purchasing the sliproll from Harbor Freight, and you could come in around ~$225-250.

It's too bad my dad doesn't still have his HAAS CNC machine. I had a cheap source of Delrin and a way to machine it. They were machining frozen custard machine barrel blades and doors with it. They had a scrap reclimation process too, which left less waste. I could have snuck in a upper/lower scruber unit once a week for almost nothing.

Day late and a dollar short!

Great question...I often forget about the REVO...Sorry about that.

Basically I can machine anything given the proper information. I have not done any design research on the REVO so therefor I would have to say not at this time ( or until I can look at one of the units ). But I will be looking into this in the next few weeks.

When I got started on this project I used the information skipbreather provided (thank you!) when I finished the unit I used it as a basis for testing.

We than began to design and redesign, and design again taking several factors into consideration such as:

Scrubber duration
WOB
Scrubber consumption (no dead spaces)
Flow direction
Durability
Various materials research to include temperature and reactivity to sorb, and CO2 etc...
Water trapping effects vs purging effect
Ease of packing
Different means of compression
I also have the ability to add a hydrophobic membrane. But there is a trade off...your WOB will increase a little on this.

We have tested our unit for WOB and it was very low ( I'm not going to release the numbers yet). We have also done a lot of other testing as well. This would be a unit that does not require any assembly.

I'm not looking to build 50 or 100 of these either. I'm looking to build 5 for testing only!!!

Now because I know it's on everyone’s mind...Do I know what I'm doing on this? The answer is I don't, but my engineers do! I recently acquired a company that has significant experience building medical rebreathers, and other devices for over 30 years...I told them what I wanted it to do, and they are working to make it meet that criteria.

I know ISC is working on a radial scrubber and that they have put a ton of research into their project. I have met Leon Scamahorn and think he's a great guy and that's why my limit is 5 and not more. I have no intention in competing against them in any way at all. The guys at ISC have my utmost respect, and it is my openion that they are paving the way in rebreather technologies. However the type of information I will be able to derive from this will help me on other projects that I’m working on.

Sorry about the ramble but after the stir I felt an explanation was needed.

Thank you

I'd be interested to see a sketch when they get close.

My concern for something to go in the Meg or APD outer case is that I can't see how a radial can work without a lot more airspace so that has to come out of the 'sorb mass. As soon as you change the outer case the costs will multiply.

I admit I can't quite see the reasons for radial either but several people who clearly know more than I do seem to think it offers advantages so I will follow the project with interest.
