My compressor has been stored in the cellar over the winter with the valve open. Each time i finish using it i open the valve and blow out any moisture , and again before i use it next time. This time as i blew it out i tilted the tank to be sure i got all the moisture out. Out came a small pool of a grey/brown liquid. Checked the oil level, and it was fine. Any ideas of what it could be??
Thanks.

sure you didn't confuse your compressor with your still again ..

yep, the liquid is brownish due to the inside of the tank rusting from condensation. It happens to almost every compressor. Shouldn't be a big deal if the tank is in good condition. When I was using a compressor a lot for work we had that sludgy puddle everyday when we drained the tank.

It's just rust from the liquid that forms in the steel tank..
It is common..

Looks like Tagger confused JPI and Jigman again. To clarify, I'm the guy that plays the bass the right side up :hihi:

Its rust like the other gents suggested. Don't drink it....

Ya gotta save that oooooozzz and seal your plugs with it.

Thanks. :btu: i figured the brown was rusty water but couldn't figure out the grey sludge mixed in. :doh: Worked fine no moisture in the line. :)

ahhh rust slime.. like what i get offa the undercarriage of my truck when I wash it.. grey poop, might be from when they painted the tank at the factory.. whatever ended up inside the tank came out with the rusty water..
I tilt mine every time when I do the tank bleed and get a nice spray pattern of rusty slop :D

dunkin doughnuts might wanna buy it :rolleyes:
