Any engineers want to try this one?
I need a small compressor, like the one pictured, to fill inflatable pipe plugs. The 4 gallon air compressor pictured here is spec'd to deliver 7 cfm @40 PSI and 5 cfm @ 90 PSI. How long will it take this compressor to fill an empty 170 gallon tank (22.6 cf) to 20 PSI? Thanks for any help.

Well, if you put one on a train leaving New York at 4:30 p.m., and its traveling at 75mph, and you put another compressor on a train leaving Chicago at 5:45 p.m., and its .......



Hell, I don't know.

Educated guess based on 22.72 cu. ft. would be 4-1/2 to 5 min. Maybe I did break out the calculator. LOL
