I put schedule 40 PVC in the ranch shop in about 1980 or so, and it still works perfectly today as it did back then. I used a hydralic hose to run form the compressor to the line for vibration. Then every 20 feet or so ran a dropper with a drain on it. In my shop now I just run a separator/filter before each main use fitting/connection. PVC works for me...easy to install, fix if damaged, cut in new line/connection and best of all much more affordable. I use alcohol cleaned pipe ends/fittings with primer and glue as your fittings are the leak points. Good luck and enjoy the not running a in the way air hose all around the shop.
