OK John, I'll take a crack at this.
Basic principles: air can hold a certain amount of water for a given
it reaches saturation (100% humidity) at which point it can hold no more water.
air is compressed it is warmed (and can hold more water). A problem can occur
use large volumes of air. The compressor runs at a higher duty cycle, the air
tank warms up (and holds more water), this warm, moist air runs out the line
to cool off. As it cools off and the air exceeds 100% humidity water condenses
the galvanized lines that you have the water will condense on the pipe walls.
If you are
spraying paint, the air is further cooled by expansion and water droplets can
the paint spray itself. Have you used a die grinder continuously for a few
will feel it get cold and will probably notice water vapor condensing on the
Now if you are not using air hungry tools you may never see this. Your
cycles occassionaly, the air which is heated by the compressor cools in the
tank and the
water condenses in the tank. As you use air, it is already relatively cool and
not condense as much in the lines or in the tools.
I think that the idea behind using coils of metal is to cool the air. The
condenses out can then be removed by a water separator. A water seperator can
water droplets but cannot remove water vapor. By following the TIP guidelines
already get a fair amount of cooling as the air travels through the pipes.
Does this make sense?
