Here's one thought you may want to keep in mind--even if you get it quite dry,
you still have to deal with the compressor sucking in water vapor and
depositing it in the tank. If the outside air is
very humid, no amount of drying the media will do any good. If it is very
humid, I would suggest draining the tank before beginning, and if necessary,
put two water traps in series on the compressor
outlet line, preferably of the molecular sieve variety.
At the garage I worked at in Florida, the compressors were outside under a shed
roof, feeding four 250-gal. tanks. We needed lots of volume because our
in-floor lifts ran on air, not hydraulics. It
was the swamper's job to drain the tanks every couple of days, and no one
thought to do it when he went on vacation. After four days, all the lifts
started getting _very_ slow. Went out to check the
compressors, whacked on the tanks to see if they had water in them, and all
four were about 90% full of water.... If it's humid, there's going to be plenty
of water in the tanks, perhaps enough so
that it's overwhelming the water trap you have on there now.
Cheers.
