We have 7 lasers in our shop, and are looking into running shop air instead of individual compressors.

Ideally, we would like 60+ PSI for each machine.

My question is what is the best way to make this work? Do we run a single line from a large compressor with T junctions to each machine with a pressure gauge and regulator? Do we run multiple lines out of the compressor to each machine?

Any pics, advice, diagrams, etc. you could provide would be invaluable.

Oh, last question, is there a calculation to figure out how large a compressor we would need to feed X machines Y psi?
