Air Compressor Set-up suggestions needed

D Man has many valid points. I would put a filter/ dryer at the compressor and at least a disposable filter at the paint gun. Air tools will last longer but are much more forgiving when it comes to moisture and contaminants compared to paint guns and the quality of your paint work. For those of you that plum your shop, the line that goes up and over your door and the farthest line from the compressor will always have the most moisture. Contamination comes from dirty compressor intake filters or worn compressors which will send oil thought the lines. Filters will filter out moisture and oily contaminants. Drain your filters often and replace the elements as needed. I always liked to turn off my compressor and open the furthest drain to drain the compressor. That will help drain moisture from the compressor and lines. Also a good idea is to use a new pvc type hose specific for painting. It will help your paint work come out cleaner and the disposable filters that screw to your paint gun are added insurance. toolman
