Compressor outlet from drain?

[Coolerman]

Did a search and read a lot about compressors, how to plumb them, adding water separators and such. I have a question I did not see an answer for.

I have a small compressor that I am upgrading. I am buying a Kobalt 2 cylinder 60 gallon blah blah. It has a drain on the bottom like most and I got to wondering: Since I will be addiing water separators to the system plus adding the line traps, why not just take the air from the BOTTOM of the tank? This means you would never have to drain the tank which I forget to do anyway.

Anyone see a problem with that approach?

Yes-It would assure the wettest possible air in all of your projects. You want to give the water as many chances to drop out as you can. Mine is plumbed to drop in the tank, then an "up" vertical, then a "down" vertical. Each vertical has a "drip leg". Put your water separator near the outlet.

I might have posted these before-but here are some pics of the drip legs in the piping.

Yes but won't the water traps get this water out of the air?

I worked at a dealer once that had a compressor system plumbed from the bottom..... under hard use all the water condensation and the heavies just added more of a maintenance headache....someone had to clean the filter system several times a day.... I would just let the majority go out the bottom and filter the good stuff from the top..... I would like to know what you think of the compressor when you get it going... I just bought one myself and the compressor seems a bit on the noisy side to be new........

Hmmm forgot about the dirt that would come through. Ok I'll plumb it out the top.

Soon as I get the garage wired for 220V, get a 40 amp breaker installed in the breaker box, install a cut-off switch near the compressor and get the manifold assembled I'll post what I think of it. Hopefully it won't be any louder than my Craftsman oiless compressor!

Just keep the water spray out of that electrical outlet ...heh is that up to code
