or that you are being more conservative on the meg than the prism diver.
What scientific evidence is there to prove your statement? As I understand it with a number of tests done on both axial and radial found there was not a lot of difference and in fact other issues may cause problems with radial scrubbers. Channelling...
When I spoke to Gordon Smith some years back he said the most efficient scrubber design was a long thin axial scrubber tube - but it was impossible to breath through. Ignoring the thermal design issues - A radial scrubber simply provides a means to shorten the length of sorb you need to breath through for the same mass than in a longer axial scrubber. All things being equal I would think the life of a scrubber will be dictated by the mass of sorb.
I accept with my Evolution scrubber than I do not get the same dive time per kg of sorb because I lose the efficiency of mass but I win in other areas such as being able to have a fresh fill more often. Swings and roundabouts and in general it does not cause much of an issue.
Must go - got a plane to catch to the South China Sea with my axial scrubber...
