temporary air piping: will this work?

[defed]

i don't think i will get my permanent air lines installed this year, but i still need to have some temporary hook ups.

my 2 stage is 175psi. right now, i just have an air hose connected to the tank. i don't need 175psi coming out of my air nozzle. so i was going to put a regulator at the tank to take it to 90psi on the output.

at the blast cabinet, i would use an air hose from that regulator to a moisture/oil separator and another regulator if needed to get the proper pressure there, and then the same thing to my powder gun.

will the regulator at the tank output be ok w/o moisture separation between it and the tank?

when i get the permanent lines in, they would be full pressure, w/ water filter between tank and stations and water/oil separator/regulators at each station, but until then, i need a lower output from the tank for general use.

If I read that correct it should be fine.

I would regulate the air at the tank to about 100-120psi depending how long the run of air hose is and what size, you may/will lose pressure and volume in the hose with long runs.

Use a water/oil separator at the end of the line near the tools, I would use one close to the air tank also, try to keep the air lines clean as possible. Since I would run more than 90psi through the hose I would use a regulator/filter at the tools also to get the proper air pressure.

Something I like to do is install an extra air tank at the end of a line. I grab up old junk compressors when I find them free or cheap! If I have a long run of line then I run say 120psi to a spare tank near the work, come off that tank with a regulator/filter etc.... that extra tank collects allot of moisture from the air also and being at 120psi it provides a volume buffer when running tools at 90psi or less.

Heres an oddball I am working on for example. I want my compressor near the main house, best power and needed here the most. My junk trailer house/shop is about 200' away.
My plan?
Run the compressor at the house, about 200' of airline at 125psi to a large tank at the trailer/shop. From that tank regulate to PSI needed, filter, and to tools.
That long run to a large tank lets the air cool and moisture condense in the lines, I should get pretty clean air from the trailer tank as is provided I keep it drained, I will filter that air also of course before the tools.
I am thinking I will bury PVC pipe about 1-2' deep for this run if I keep it as is, but I want to dig out the side of a hill and move that shop trailer so untill I decide nothing gets burried yet.
In any case the trailer has low amp power lines far from the source so i do not want a high amp load there. I can run a normal sized oven fine but trying to run much else at once is too much.
