I had posted most of this below in a question about regulator brands and only Charles answered, but only about the brands, so I striped that out and reposted the rest of it.

Is it better to have regulators and dryers at the drops or to have them close to the compressor? Also, do you dry before you regulate? Seems like the triple units dry, regulate, then oil.
I guess I need to back up a bit and talk about my configuration. My compressor is going at the front right side of the garage. In front of this I have a 10' deep, by 8' wide cubby that I just put a 'L' shaped bench in. My side of the garage is the outside side and the compressor is on that side. Across from the compressor and up the 4" rise into the cubby is the end of the bench that goes back the 10' and across 8' to the outside. Between that end of the bench and the compressor is a 36" door and the panelboard. My compressor is a 80 gal. 240V 2 stage Delta.
Right now I'm thinking of going up between the compressor and panelboard with a 10' stick of 3/4" black iron pipe thru the ceiling into the attic. I'll tee and take one side at 3/4" about 20' towards the garage door and come down with 3/4" about 2' inside the door on the outer wall. I'll have a tee with a 6" dirt/drip leg and a 3/4" or 1/2" ball valve on the bottom. The other side of the tee will have a 1/2" NPT regulator/dryer and a pair of disconnects. This is where I'll hook up to a pressure pot for a sand blaster for use outside. The eventual sand blast cabinet will sit next to it. Back at the first tee in the attic I'll turn 90 degrees and go across and down next to the sink. Same dirt/drip leg with ball valve and regulator/dryer after which, another tee and from there on, all 1/2" pipe. One side of the tee will go down and be for the front of the garage, the other side will turn and go up under my shelving above my bench, teeing off 3 or 4 times with drops down 12" or so towards the bench.
I figure the regulator/dryer at the bench will be about 25' from the compressor as the lines run and the far drop will be about 40'. All 3/4" horizontal lines will slope away from the compressor. Since I can't come off the top of my 1/2" lines under my shelving, I won't be sloping that line. Does this sound like a decent layout?
After some thought, and the inability to find US iron fittings, I'm rethinking about going with copper and just trying to be more efficient with my layout. I'll tee for the future media blasting area and only do about half my bench. In my drawings below, the air piping is single line, the dashed part is future.
