just bought a pre fab 14 x 28 garage and want to run a compressed air line from my 60 gal compressor in the basement. The line will run through the basement then underground out to the garage. My main concern is condensation in the underground portion and how to properly deal with it. My plan is to run Rapid Air nylon air hose through a PVC conduit to help protect it and give me access to it in case of failure in the future. I could then pull it out easily and route a replacement hose if needed. Anyone have any experience doing something like this? How did you deal with the condensation in the underground line? I plan on sloping the underground portion towards the garage( in the direction of airflow), but am not sure how to drain amy condensation at that point before it travels vertical into the garage.
