You have it exactly right. You have to treat compressors like voltage sources. CFM as amps. The restriction is the load. You can have a 10,000 CFM compressor as long as the PSI does not exceed the rating of the airspade.
I have seen guys having trouble blowing fiber and going from a 400 CFM compressor to an 800 CFM thinking it is going to “push” the cable better. As long as your pressure drop from your hose is not a huge problem, you only need the lowest CFM you can get away with.

I got the 105cfm variant because its whats available, they do have 150 and 225 cfm My partners compressor is 275 cfm. Ive never really looked at controls to see if its adjustable beyond just the valve since we use it for blowing material only will a 105 cfm nozzle just restrict flow or will it tear it apart? Sales guy said it would be fine, but sales guys are dumb. Im dumb too, I have issues comprehending the difference between PSI and CFM, I assume its a volts/amps comparison and psi is applied volts, CFM is available amps for consumption, but its the restriction component im struggling to comprehend and dont want to blow up a $3k tool. -------------------------------------------------------------------------------- -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
