Get with the program.  We're not discussing pressure differential, we're 
talking canister packing.  It was reported that the Drager spring-loaded 
canister was not ideally designed for the fill-line that Draeger 
recommends.  The concern was that pressure from the springs against the 
absorbent might lead to canister distorion and possible leakage.  My 
contribution to the discussion was to underscore the importance of proper 
canister packing, to avoid "settling of contents" and subsequqnet flow 
channeling.  I suggested that the engineers at Draeger have enough 
experience that they are not likely to design something incorrectly, but 
it seems I may have been proven wrong.
