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 would be inclined to look for a replacement,if your receiver is rusty not much need to proceed further and it will become a safety hazard,auto drain valves are great and work well as stated.
Go for the biggest unit you can afford and fit a water separator and autodrain,make sure you use a minimum of plastic hose as it helps little with moisture problems. Go for a 10 to 12 cfm unit and you can do pretty all you may need,if you need more capacity add a remote receiver for light sand blasting for example. My previous experience was with 2 large dual stage intercooled 3 phase compressors making 30 bar pressure max running 2 very large air start tanks....huge amounts of water made like you wouldn't believe. |

From what I've seen, most compressor tanks are not painted inside so rusty water is inevitable. My previous experience was with 2 large dual stage intercooled 3 phase compressors making 30 bar pressure max running 2 very large air start tanks....huge amounts of water made like you wouldn't believe. Working in a power plant that uses piston engines running on natural gas? ( Or maybe turbines on nat gas ) |
