Then I ran 3 legs of copper off the compressor, up down....up down....up down..... and back up with a ball valve at the bottom of each drop. Then I connected it to a standard filter kinda like this one (this filter might be redundant but I figure it's better to be safe than sorry if painting)
The heavy lifting is done by the Motor guard and 2 stage desiccant filters. I attempted to just use that little filter I posted at the end and after a couple compressor cycles, the moisture just over powers it and it's useless. It's really just meant to be a last line of defense. After I did this setup, I no longer have any moisture when primering or blasting.
