okay, that makes sense. understand now.

i was thinking of four stations. one on each wall or corner. the
compressors are going to have their own small room on the south facing
porch of the new shed.

yes, very true. more oil-free uses than just spray painting.

ries, thank you very much for the above pdf. that piping layout is just
what i was looking for.

ries, did you use black steel pipe in your air system?

i picked up a good amount of copper pipe and fittings at a bankruptcy
auction. i have 30 10ft sections of 1/2 inch copper pipe of type m nsf
61. i have 40 10 ft sections of 3/4 inch copper pipe of type m. i would
like to use the copper pipe for the air system. if type m copper pipe is
too thin to use i would switch to plain black steel pipe. i would go
with weld fitting instead of threaded. not as easy to change as threaded
but easier to install.

the thought just occurred to me if pex which is used for radiant heating
systems and for water systems in some locals would be usable for air.
can pex take 175 psig?
