Compressed Air Piping

**427yenko** · #1 Today, 02:22 PM

Hi everyone. Looking for advice on the best air piping to use for garage compressed air system. I would like to conceal in the walls and above the ceiling for the installation method. What is everyone using?
Thanks!
Bob

I used black iron pipe throughout the garage also behind the walls. I used T111 exterior siding inside held on with sheet rock screws. I collect signs so that's why the siding. The screws so you can get in there if you need to. It's been 12 years & no problems. I also ran the electrical behind but mounted it about chest high in case something was stacked on the floor....Joe

Black iron because it acts like a cooling agent, where plastic, or rubber insulates. I had a diagram I posted before that shows the proper routing and drops, but I can't find it now.

My "Rapid-Air" Plastic system has Constant issues, Sad I went this route now.
"MAXLINE" system.

Black iron or type L copper pipe.

I ran all the piping high & when it stubs out at the wall each one has a ball valve shut off & also a drain about a foot below the tee coming out of the wall....Joe
