There are Aluminum Air Lines systems made specifically for Compressed Air Applications , Cut and Push fit fittings, elbows etc.....Only way to go, Flows more air than steel and "No" Rust issues.....When we did our New Building that's what we used (along with a Screw Compressor and a Chiller Dryer)......"All" the Air related issues are a thing of the past.....Don't remember the name of the system right now, I'll find out and Post later
