John,I suggest a small inline filter just before the gun. They are inexpensive, andoffer a last chance filter.GaryNX308MBSent from my iPhoneOn Aug 8, 2013, at 11:34 AM, John Franklin wrote:> > I have a run-of-the-mill air compressor with a regulator/oil separator and anadditional water separator, all bought from the big-box home improvement stores.Is that enough filtration to spray paint with either latex or aircraft dope?I've heard that any oil that gets into the paint is really bad news.> > Thanks,> John Franklin> Prairie Aire 4TA0> Needville, TX> > > > ________________________________________________________________________________Subject: Pietenpol-List: Re: Painting question

In TX, your biggest enemy is going to be humidity. The best way to get rid of that is to run the air through a copper coil in a bucketof cold water, then a regular water separator, then a small inline dessicantfilter right by the gun. If you don't have that readily available, even all the air hose you have in a bucketof cold water. The goal is to condense the water vapor to particles, whichthe filter can eliminate. The little dissicant filter (a small little thingwith a particulate filter and dessicant, you know when it saturates by a changein color). Most compressors aren't blowing out a lot of oil. If you usehoses that have been used on a system with an oil mister, that's a differentstory. But the little dessicant filter should get the little that might makeit through. I've never noticed any.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Painting question

Here's the inline dessicant filter:http://www.harborfreight.com/inline-des ... 5.htmlIt's important to use a "pre filter" with the bucket of cold water and water particleseparator because I've trashed one of these in a flat two minutes withoutit! I now use a large dessicant filter, about the size of the water particle separators.You can remove the dessicant and dry it out in an oven. It was about 80bucks ten years ago, not sure what they run now.Here's the regular filter:http://www.harborfreight.com/12-standar ... 279.htmlIf you can cool the air before it enters, you can literally see it fill with wateras you use your air compressor. For MAXIMUM effect, route your air directlyfrom the compressor pump, through some sort of cooler (on my GMC motorhome'sair suspension system, this is a 5' length of 1/4 copper line snaked aroundthe pump itself, and is cooled by the pump fan), this filter, THEN your tank.That will keep the majority of water out of your tank, extending its life significantly.I don't know why compressors aren't just built this way...Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Thu, 8 Aug 2013 12:15:47 -0700 (PDT)
