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! |

Air is like a sponge, compress it and water vapor has no space to reside so it falls out, this is normal. The more ambient humidity and more air you use, the more water you will get. The air compressor isn't making water from hydrogen and oxygen.
Your current moisture filter is becoming overwhelmed, you might need to run 2 in series or a larger capacity one. Better moisture filters have an auto float drain and are worth the extra $. A second tank and / or hard piped shop with drain legs can be helpful as well. If the line from the compressor pump to tank is close to the air outlet, water does not have a chance to fall out of the air and will be carried over to your moisture filter during times of high air use. If you get a timer style auto tank drain ,while inexpensive, they waste air as they are always in operation even if you are not using any air ( RE: they will drain even if there isn't any water. ) . The better ones ( $ ) drain only when there is water and won't let any air be lost in the process. Compressed air is an expensive 4th utility ( Electricity, water, nat gas , air ) so fix those system leaks if you have any! |

I have a short piece of hose I can use to relocate the filter farther out, and also add another filter. I might add an in-line filter as well. Still looking into the tank drain. |
