Hi, A friend of mine has a 60 Gallon Snap On Air Compressor, 5hp, 18.5 CFM @ 100 PSI.

I was looking at buying a DV Air Compressor that is 5hp, 13 CFM @ 125 PSI. How would the extra 25 PSI affect the CFM rating? I'm not sure how to calculate. What CFM would the DV produce at 100 PSI?

Thanks!

 

Generally the CFM rating is higher at lower pressures, so it's probably pretty close to the Snap-On's rating.

 

not something you can calculate W/O manufactures performance curves. But Jared is right. The performance is probably pretty similar.
