Glenwood, Mn | ryan elias - 3/4/2026 03:25 Yes. Big difference with a loop system
More line also adds capacity storage/tank wise for burst use as the line itself is storage. So if you can loop you get volume and capacity. Worst case you can add a receiver tank at the end or point of use. I have a 30 gallon tank from a dead air compresser on wheels I can tee in at any point in the line to get extra capacity. Biggest gun we run is 3/4. We only run 110 psi line pressure but 175 psi adds significant capacity as well. Our shop is 60*144 and the compressor is in one corner. Longest run for the 3/4” line the would be roughly 296’ ( loops 7/8 around the shop as the office is in the way). For air nozzles and what not a ok. Definitely won’t run a 3/4” impact but the back of the shop is dedicated to small engine repair so the 3/4 impact doesn’t go there.
Even 60 ft away at 110 psi 3/4” Impact will starve for air on 3/4” line without the additional tank. I use the 3/4 impact once or twice a year. So no big deal.
If you are a dedicated repair shop, I’m putting in 1”. My shop is combo CNC and 10% farm repair. Japanese CNC air regulators specify 120 psi inlet so that’s why we run 110.
Edit. Reviewing the chart KS posted stating line size and cfm I think my issue is likely that my main regulator can’t output the volume required. By the chart posted, I should have more than plenty for my distance and line size but run out. The pig/receiver tank that is post regulator, solves this issue in high cfm situations. Learn something new everyday!

3/4” vs 1” for shop air hardline.
