If anyone has any experience with air compressors, I'd like some help/advice regarding the following:
I have a 30 gallon Craftsman compressor (built in 2008). 8.6/6.4 CFM @ 40/90 psi. I have a moisture filter before the hose hook-up. 1. RUSTY WATER IN THE TANK When I drain the tank, there is always rusty water, maybe 1/4 cup or so. I know this is normal, but how much is supposed to come out? Is there an standard/typical amount that is normal? 2. WATER IN THE HOSE I also get air in the hose that comes out whenever I use air tools. I get a few drops every few minutes. When I bleed the moisture filter, no moisture comes out. 3. IN-LINE FILTER I'm thinking of getting another in-line moisture filter. I will be painting some parts soon and want to make sure that I don't spray water with the paint. What do I look for in a decent, in-line moisture filter? Thanks! |

I agree that water needs gravity and distance to cool down and fall out. I run 3/4" copper pipe to all three outlets, with drains down below on each. I have about 70' of pipe running along the ceiling and down to the outlets in 2-car garage. For painting, I use a Devilbiss desiccant snake hose (~$30) coming out of an HF swirl-pot filter, and then a MotorGuard (model #DD1008) see-through filter at the gun. These MotorGuard filters let you see the desiccant as it turns from blue to pink as they colllect moisture; the little pumpkin-style gun filters only let you know there's a problem after the paint dries. Ask me how I know... the little pumpkins are about $7 each while the MGs are about $15 each. Money well spent.
