John, that is an excellent point. One way to check is to put a pressure
gage after the regulator, and look at how it behaves under maximum flow.
The regulator that came with my el cheapo (Sanborn "Black Max") compressor
was not up to the task, pressure would drop considerably when I used my die
grinder. My solution was to remove the pressure gage from the tank, drill
and tap it's bung to 1/4" NPT, and connect a hose directly to the tank. I
use that hose for tools that need maximum pressure and flow (die grinder,
impact wrench, etc.), and the original fitting for regulated air pressure
and lower flow.
