Default Home made air / water seperator

Hi Guys,

Can you all show me your home made air / water separators that you painters use for your guns?

I have a $50 filter on the output of my compressor, AND a filter on the inlet of my gun but WOW there is always an amazing amount of moisture in the lines whenever I take the gun on or off the hose.

I have been thinking of buying some copper tubing and making a desiccant snake, but before I do I would like to see what you guys have done before I try to re-invent a wheel.

Adam

Aw come on, all of you guys are tool nuts and NO ONE here is a paint enthusiast?

Paint Guns are tools... Hell, I don't shoot professionally and I have four Iwatas...

The only one I can think of was someone that made a desiccant filter using an old propane cylinder.

Do a search it should show up.

Well, I was thinking of making some kind of crazy up and down copper snake that has water outlets at the bottom of every horizontal section, meaning that the moisture would collect there and be drainable when ready...

I want to see how some other painter people have done this. I run the $50 Campbell Hausfeld thing on my hose right now, but I do notice plenty of moisture in the hose when I switch guns or disconnect something...

AND I think I created a bunch of light nibs in my base coat because of this screwup! Aw well.... Let me see what you guys do.

If your air line drops come off the top of the supply or perimiter line,and have a drainable drop leg at the regulator it wont be a problem,also,the perimiter line should fall back to the compressor.Not trying to be a smart a&^,just look at your air instalation,then decide if your separaters are not adequit.I had a compressor install in the ohio shop and in over 30 yrs I never had any water in the paint booth line.

you also can't have a your first one on the compressor you need to move them away from the compressor as you will run in to a tempature problem as the comp will really heat up the air and even the tank and line close to it.

Here is a link to another thread I started about air dryers http://www.offroadfabnet.com/forums/...ead.php?t=6684 . I hope it's ok to link, just easier than retyping everything. I never did get around to building one but did a lot of research. If you do some googling you will find TONS of different ideas. One of the ideas I liked was putting the cooler in between the pump and tank, many thoughts on this out there.
