.... Till then I believe that the 14 % per ata of depth is a reasonably good approximation of the depth effect on a scrubber with a given charge weight (given a previously validated scrubber duration, at analogous dive and work conditions, but another depth).
......
Given that theres now been published Ansti-results for different sports Rebreather, I for one would like to see some simple tests performed (just on the major different scrubberdesigns ie. radial, axial and EAC) that meassure:
a) duration @ 40msw, 4dgrC, 1,6lpm CO2 (or 50-60m) - divephase
b) duration @ 6msw, 4dgrC, 1,2lpm CO2 (or 10m) - decophase
And test really interesting:
c) 50% time of a) at samecondition. Then total time to breakthrough with the rest of the test being performed at conditions b).
This would correlate to sportsdives, where the Rebreather is used throughout the whole dive (ie. no bell or surface supplied Deco). The difference in time between b) and c) would also tell us how much of the scrubber comes back to life when ascending.
I dont care on wich unit as long as it is axial
Sorry if test as above has been conducted allready, and I'm just not aware.
