I have a 5 hp compressor, relatively new, and it won't sustain the demand
from any rotary sanding tool. Puzzled, I finally determined that the
sanding tools generally require about 12 cfm @ 90 psi -- but the
compressors generally put out 12 cfm @ 80 psi. I'm really disappointed that
the measly 10 psi difference won't run the sander. It will run straight
line sanders quite nicely, though. I'd appreciate input on any rotary
sanders (commonly called DA's) that anyone has that will operate on less
than 90 psi.
