It's actually both I believe. Draeger is the englicized (sp?) version of 
the gerrman name that has a "umlaut" on the "a" (2 dots side by side)..
German tekkies, correct me...

dive, but I do it about every three hours.

is putting so much pressure on the canister as to leak water into the center
section and scrubber that sounds much more serious.

Within the center opening of the donut shaped scrubber canister are the three
O2 sensors.  Below all of this, well protected from counterlung eating fish, is
the counterlung.
