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.

This is simply false. Heating causes *evaporation*, not condensation.

Vapor condenses into liquid when it is either compressed, or cooled, or both.
But *never* when heated unless simultaneously compressed by an even greater
factor.
