I used an auto AC condenser and it works very well installed after the tank. Picked it up from a junk yard for 20 bucks and just needed two standard compression fittings from the hardware store to install it. I also use seperate water separators at the end of each line before any tool. The drop right after the condenser collects plenty of water but no other separator has seen even a drop so far and I've tested it over the entire summer. Some said a condenser would be too restrictive but I've had no problem with the blast cabinet or any HVLP paint gun I've used. I have an electric radiator fan that I thought would be needed but so far it doesn't seem necessary for the condenser. I mounted the condenser in line with the compressor motor so the fan could also aid in cooling it as well so I'll probably install it before next summer.
