Plasma like clean oil free air, air tools like a little oil with their gulp of air. For the small home shop this can be a minor challenge but a critical one...Here is how I did it:

Must be nice to be able to afford a plasma, one day I'll have one, for now I'm stuck with torches. Nice write up though.

Yes, did you read the part about the two air hoses, one is yellow for air tools and one is red for my plasma cutter. The oiler is attached to the hose itself at the point where it attaches to the air tool which keeps my hose from getting gummed up.

That looks good.
I used to install and repair air compressors.
Be sure to drain the air tank often, I've seen the results of a tank that blew up, not a pretty site.
How's the water issue on those lines? If you want, I can give you some hints on lowering the amount of water that gets to the tools.

i'll take those tips!! i have a 135 psi unit w/ a 13 gal tank. not really powerful enough for the d/a and other sanders and my die grinder runs it dry; but for most ratchets, impact guns and nail guns, it does the job fine.

Ian, post up for everyone's benefit. I know I run air tools plenty, air nailers for roofing work, and we used to run water seperators on ours, and of course drained the tanks on the compressor daily. We tried an inline oiler, but it didn't work so well with our system. We were running 5 or 6, 500'x1/4" hoses on reels, so it was tough to keep enough oil in there to supply that much hose, so it just turned out to be easier to oil them individually. Not to mention we were running ours constantly, roughly 8 hours a day.

Here's a link that I found to show the way to run air lines the best.

Do not reduce the air line size until you get to the air dryers, just before the quick connects.

Put the dryer then the oiler in line to keep the air tools lubed.

I think you can see the importance of running the lines from the top of the piping, and a drop tube at the bottom. Water is you enemy.

As for those nail gun compressors that the roofers use, you have very little choice on where to put the dryer. Oilers will do nothing w/ the amont of air hose they generally run. Oiling the tool daily, or twice daily on long use jobs, is the best.

The longer the hose, the more pressure will drop. The more bends, the lower the flow, The smaller the piping, the slower the flow.

Keep all piping the same size as the outlet form hte tank, this is usually 3/4". If you reduce the size of the pipe, th eflow will suffer. If you increase the size of the piping, the pressure will drop.

Thanks for the tips...albeit moisture in the lines is not a problem here in Scottsdale, AZ. Its almost Dec and we are up to 2.7 in of rain this year in a wet year we get 8. Humidity is LOW! I used to live in Miami...sure do like it here.
