Moisture Removal
For those of you who are spraying primers, base coats and clear coats (doing their own paint job)...what type of air filter are you using to remove contaminants from the air line? What is your setup...I need to set my garage up so as to remove all the water from the air lines before I start priming.
Thanks

Get a really good water separator, bought at places like Home Depot and Lowes. Don't skimp. Money saved here is bad, as the cheap little ones don't do much good.
Also, the paint counter at Oreilly sells little inline plastic bulbs that go on the bottom of the gun and help get more moisture out. Only good for a few hours of use...so buy a few. They are orange, and thread inline at the base of the gun.
Between the water filter at the compressor, and the filter at the gun...you should be fine.

I use 2 filters in-line from Grainger. One is a desiccant drier with replaceable media: http://www.grainger.com/Grainger/wwg...mId=1612528324
The other is a regular filter with 5 micron replaceable element. http://www.grainger.com/Grainger/wwg...mId=1611725373
Both filters cost under $100 and the replacement media and filter is about $20 for both. Mine are about 4 years old and replacement parts are still available. I replace the desiccant media and filter for every paint job. Occasionally I'll use a disposable filter at the gun. I don't use these filters for operating air tools.

Once you install a water separator of whatever quality make sure your line length is sufficient for moisture to be withdrawn. Most won't work within 50 to 75 feet of the compressor. You also have a better chance of less moisture if using HVLP gun technology.

Here in FL you need at least 20 foot of hose or pipe between the tank and the filter/water trap. You have to give the moisture time to condense in the line. Water traps remove water, not moisture.
In addition I use deVilbiss "snake" dessicant filters. So far so good...

Here in Houston what I did was: water drain and steel pipe from the compressor up to the shop ceiling, 20' across the ceiling to another drain, 20' back, down again to a 3rd drain, into a dryer and separator (TIP Tools), and finally a coupling to the hose.
