That media is UNDER oil and moisture can NOT be vacuumed out of it once attached.

i can agree with the idea of shortest time possible. in the short time it takes to run to the shop is not gonna use half or even a quarter of the dessicant up. i belive it can be removed, but thats fine, i can admit the possibilty that i am wrong here. my biggest argument is on the new dryer being so well sealed that it will hold pressurized nitrogen. NOW, if we are talking a nitrogen "purge" i will call that plausible, but i will also argue that there is a great possibility that air has mixed in that purge.
