[PSUBS-MAILIST] scrubber

[hank pronk via Personal_Submersibles]

Hello All,
I am having trouble with my scrubber, I am using absorbent for an anesthesia scrubber (CarbOlime) .  The scrubber works excellent when I use lung power.  Lung power keeps the sub at 1200 ppm or less, with in seconds when I switch to the fan the level starts to climb to over 3000 ppm. Am I using the wrong absorbent.
