1/2" or 3/4" Air System

[TFOGGER]

Back when I was operating concrete plants, air systems controlled valves and rams for aggregate gates, chutes, bin vibrators and more. All we used was 1/2" iron pipe lines. It's the capacity of the air compressor that delivered the power. BTW, I strongly advise against using PVC lines as they can be very dangerous when they fatigue and rupture. Do a little research before going that route.

We've used 1/2 CPVC for air line in the shop for more than 20 years without a failure. Our shop air is at around 135 psi, and we drain the system every couple of days to get the water out. That being said, we don't use a lot of air, except for the brake bleeders, occasional use of the blast cabinet or a DA, and the bike lifts. Compressor is a 5 horse 80 gallon, running on 240.

Pretty much same experience for me. Have had couple blow outs in counter top shop over the years, always failure at glue joint, no ruptures. I keep pressure down around 100lbs to minimize wear/tear on nailers.

Drain drops, regs and water separators at each station.
