[PSUBS-MAILIST] Manual Scrubber

[Jon Wallace via Personal_Submersibles]

 I agree with Steve, would be a nice addition to the Community Project page.  Seems pretty intuitive in terms of putting it together but can you send me a list of where you sourced the parts?  Part numbers if you have them?

Hi all.Ive been experimenting with various manual "breath through" scrubbers for use in an emergency, and i have finally come up with a solution that works for me.  
Ive been testing an anesthesia scrubber cartridge.  This has turned out really well.
Previously I made breathing tubes and masks that utilized the main scrubber, but the trouble is that they were all too difficult to breath through.  I made one with a battery electric fan to assist in breathing and even one with a CPR bulb in line to assist.  Nothing really worked, but this new one is really good.
Its a cartridge for an anesthesia machine and has spherical balls on CO2 absorbent which makes it easy to breath through.  I used various different masks until i got one that was easy enough to adapt to the hose and comfortable.
I only did half an hour as it was so hot, but I got cabin CO2 from 5000ppm to 600ppm I think.  The main scrubber was on, but obviously the manual one was taking the most of it.  

Anyway, I feel much more confident I can control CO2 in an emergency now.
If anyone is interested, i can send more details of the parts used and modifications, which were super simple.
Pic attached and a video of me using it.  Skip to 7:35 for the manual scrubber test.
