Gunsmithing Air System for Cerakote?

Devilbiss DAD500 is what I run second choice would an RTI elimonator 1000. You need a good desicent dryer and charcoal filter. Both of these units are used in thousands of paint booths around the country. A mistake most people make is their filters and dryers are too close to the compressor. The air coming out of the pump is hot and most filters are most effective with air less than 100f. You should have at least 30-50 feet of pipe before your dryer. Unless you have an after cooler. Also drain the water from your tank regularly or install an auto drain.
