i have a 6.5hp 60 oiless compressor. my total run with 3 drops will be less than 40ft. im using copper for sure. what size line should i use? my garage is 20x22. im gonna tee off the last drop for my filter/reg. into my hose reel. the top line will be slanted towards the last drop. does it sound like this will work ok? if i left anything out let me know. thanks for any info. i'll try to post a drawing later of what im trying to do

There has been a lot posted on this site about air systems, size depends if you will be the only one working .If only you 1/2 should be fine for most work, A big sand blastaer you might want a 3/4 line to it. you will want a good drain for the tank. usually best to do a cooling system and line drain close to the tank. and an end of line drain on the runs, outlets should be an inverted U , First up then down to the outlets, You are not in the dry east Wa desert,you might consider a refrigerated dryer if you plan on using a plasma, and doing paint jobs. A little bit of moisture caused $100 damage in seconds. in the working end of my shop (40 x 120) we used a copper system from a factory demo job, got paid to take it out. 3/4 out of the tank then split into 1/2 down each side of the work areas.

Thanks for the info. I was planning on the upside down u on the drops. It will be only me working in there. I will have a filter and reg. At the end at the drain side. So should I put another filter in and where? I drain my tank after each use.

I use a couple of the filter-reg from the factory and they have a fitting on each end and a short coupler hose so they are portable. I use unfiltered air to blow out the floor, etc just use a seperate new hose for the paint guns and plasma with the filter reg.

My compressor is a craftsman so maybe I'll put a filter after my flex line and the other at the drain. Thanks for all the help. Ivan.

I had the same size Craftsman Oil-less compressor and after about a month, it disintegrated. I had not really looked under all that nice shrouding until this happened and discovered a disintegrated piece of junk that I would not have paid $50 for had I known. Before you go to all the trouble of plumbing it in, you owe it to yourself to remove the shroud and look at that flimsy compressor wannabe. If it is new, you probably will take it back and get a real compressor.

I already know its a pos. I got it as a gift so I'm gonna run it till it dies that way no one else has to deal with the misery.

I run a 3/4" rubber line from my 60 gallon to the 1/2" copper running up the wall, and around the garage with upside down U drops. I used M copper (Or the cheapest one, can't remember if it's M). Holding fine at 150psi.
