Water vapour condenses when the water/air mixture is
compressed...ASSUMING the temperature stays the same...which it won't
as air temperature increases when the pressure does during
compression...... so we wait till it cools to the original ambient
inle temperasture.... then it condenses.

Water vapor condenses regardless of pressure. Ever take a glass of ice
water out side on a hot humid day? You get condensation on the cool
sides
of the glass. The condensation is formed when the humid air that has
been
heated up during compression, enteres the cooler compressor tank.

That's what I said, and I quote, including some fat, laptop induced
typos: "so we wait till it cools to the original ambient inle
temperasture.... then it condenses"

IOW.. when it cools.


OK, I misunderstood, This part threw me, Water vapour condenses when the
water/air mixture is
compressed. I probably took that out of context. Sorry.
It'lneverhappenagainuntilnexttime. ;~)



Have you ever wondered why portable air tanks seldom if ever have no
bleeder valve for releasing water?

I had never given that any thought... but I think that's related to
duty-cycle.. just not enough air going through to matter.

That's probably ture too.
