Close but not quite. It's the act of compressing the air that causes
the
water build up in the tank.

It's the heat generated during compression that causes condensation to
build
up in the tank. Compress air with out changing the temperature and you
have
no condensation during that process.

Yeah, we really do need a good isothermal shop compressor on the market.

.... until then we'll have to live with Charles's Law.
