<VV> Drying Agent

[FrankCB at aol.com]

Tony,
    Most likely they are Silica Gel material which is a  commom drying agent 
usually packed in permeable bags with all sorts of  things.  I find a lot of 
small ones in my vitamin pills.  Many times  they are packed with electronic 
items you buy NEW.  As you found out, they  do a good job of removing mositure 
from the air.  And they can be  regenerated by putting them in an oven to drive 
off the mositure.  Just  don't make it hot enough to ignite the bag material.
    If a little heat is good, a LOT is NOT  better.<GGGG>

The  drying cannister was an oddity, originally (according to what I 
was told)  used in the medical profession to absorb moisture from 
air/O2 lines, made  of aluminum and about a foot long with thick 
polycarb o-ringed caps on the  ends with brass NTP fittings, held 
together with threaded rods and nuts,  had what was evidently a foam 
dust filter in each end, sandwiching a sack  of what looked for all 
the world like kitty litter, only very light weight  and tan-brown in 
color.    Not sure what it was but it  worked.   It evidently was made 
the way it was so as to allow  easy changing of the drying bag of 
whatever it was.   I used it  on the downhill side of the pressure 
regulator...  didn't wanna put a  bunch of pressure on it even though 
the guy who gave them to me said  they'd take as much as 200 lbs.

I still have several of these things in  the basement...  next time I 
paint another car one of 'em goes back  in line.   They stopped ALL 
moisture, nary a hint of a drop got  through no matter how humid it 
was.     I was told that you  could reuse the sacks of crumbly by 
baking them in an oven for a while at  around 200 degrees according to 
the donor.

...anybody able to tell  me just what these things are and what they 
were originally used  for?
