I am looking to move my compressor to the other part of our building. There is a interior wall with a 1 car garage size spot beyond that wall(enclosed room with ventilation) I am wondering what you guys think would be the best way to plumb the air. It is about 50' back, then 25' over then through the wall and about 30' to the "compressor room". How about Galvanized pipe? Hose? I will be running my respirator off this line as well. Are there any types of pipe I shouldn't use for breathing air purposes?
I was thinking once I get past the interior wall I would use 1 1/2" pipe with a downward angle with drop-offs for moisture? Any suggestions would be great. I have a 375cfm compressor. The compressor is about 15' in front of the blast pots right now connected with a 25' 1 1/2" hose.
