The rubber line goes out to the garage and connects to 30 feet of 1/2" pipe in the garage. I cant run metal lines out to the garage due to a massive concrete patio on my back porch. Is the 1/4" air line going from the house to the garage restricting my air flow? Can I pull 15 cfm through that line?
From my experience, that 1/4" line is too small for even short runs. Replace even the hose to your air tools with 3/8" and you will be amazed how much better they run. I say go to a minimum of 3/8" line. Using the pi R squared formula, you will see that 3/8" will handle twice the volume of 1/4" . For that run, you may want to get some 1/2" air line. Not sure where to get it from in your area, but I know it is available. Maybe check with a heavy equipment dealership to find out where they get theirs. 1/2" air line is used to power all heavy air tools, such as 1" impacts. Possibly your local NAPA auto parts store will be able to help you out.
