I use a long air hose (100'), for the air to cool as much as possible, then it
hooks about a foot from the bottom of a vertical 1 1/4th inch by 7 feet tall
galvanized steel pipe. Also on the bottom of the pipe, there is a small petcock
to drain out accumulated water. On the top of the pipe, there is a quick
connect, to hook up the air hose running to the sprayer. Immediately before the
sprayer, I use a combination desiccant/filter, available from NAPA.
In painting a large project, it might be necessary to use two filters, but with
some creativity, the cases can be split, the desiccant dried, and used for the
next project. Using this approach, I've never experienced any fish eyes.
I think the large steel pipe helps so much, because the air slows, and also has
some time to cool. With the air going in near the bottom, and moving slowly,
there is no possibility of water, in liquid form, to make its way into the last
air hose. The last bit of water vapor in the air will be caught in the final
filter.
