compressor lines let see them

[DesertCat]

Most of the ideas you will hear about are more complex than they need to be.

Not the first time I have posted this on this site:

every body shop I worked at had a large diameter standpipe (like 4") right off the compressor that went to the ceiling. A smaller diameter pipe tee'd off the top and ran downhill at least 20 feet with about a 4" per foot drop (angled downhill), which tee'd into near the bottom of another 4" standpipe. The final airline takeoff was well above that tee.

The reason? Lower velocity in the large diameter standpipes, high velocity in the smaller downhill run. Finally the moisture crashing into the second standpipe (again low velocity so the droplets tend to fall out of the airstream.

This was all done with black steel/iron pipe for cooling. Petcocks at the botton of the standpipes and a simple water trap where you hooked up your air hose.

I always installed a mini trap on my guns... very rarely had a problem.
