Joe and Mark: you are both right.
Mark's definition is the correct one of channelling. Many axial scrubbers suffer badly from channelling when the scrubber is horizontal.
Joe rightly points out that the rEvo is not as prone to channelling as most axial scrubbers are, because it is oriented vertically when the diver is prone, and also has opportunity for the gas to mix between the two scrubbers, so raw unscrubbed gas does not go through a channel on the second scrubber even if both were to channel.
However, I would like to see the figures for when the diver is vertical, such as in a deco reading his fishing journal or whatever he gets put onto the trapeze for amusement.

Alex,
I really don't see the rEvo channeling.. When you following the packing procedure, the amount of sorb you is is very consistent.. so once you get the technque down there is very little variation from scrubber to scrubber.. so I see you either pack it really badly (probably by not having someone show you the technique) and you have a loose fill on many dives or you get a good fill.. Following the techniques that are taught in the class, I havent seen a poorly packed scrubber yet..
