When a lawsuit a few years ago caused air compressor manufacturers to
quit exaggerating their horsepower ratings, did it also affect the way
they advertised CFM air flow ratings? Because my old, pre-lawsuit
120VAC oilless Campbell Hausfeld WL600602 is rated for 6.1 CFM @ 90
PSI, while the biggest oilless they currently sell is rated for just
3.8 CFM @ 90 PSI.
Shouldn't as they're independent measurements if actually are measured;
of course, if they weren't... (Note I didn't say the hp is independent
of what the compressor is capable of only that measuring them air output
isn't the same measurement as the engine/motor hp).
That's what I thought, so this really puzzles me. But back when all
companies were grossly inflating their HP ratings, the HP ratings kept
going up even when the CFM ratings stayed the same or even dropped.
For example, a "5.0" HP Campbell Hausfeld was rated for about 1.5 CFM
@ 90 PSI less than my slightly older "3.5" HP model. Both of these
were oilless, single-stage, and made for 120VAC, 15A. Inconsistent
