One thing you need to look at is you should have a minimum of 50 ft of copper line on main line this is needed to help the water vapor drop out of suspension or you will get water past your filter and into your tools or paint gun.
You could have a 1000 ft of copper line and the air will still be saturated with water. The 50 ft will drop it close to room temp so, yes, water will condense out but any pressure drop and more water will condense out.
