Yes, this page says what you say it says. So who the heck is
cleandryair.com and why should I believe them over what is obvious, what
is common practice in the air compressor industry, and what is taught in
every engineering school?

I suspect this page is trying to redefine some terminology to give themselves
some kind of business advantage. I have no problem with this, but don't expect
me to believe it.

This page correctly explains that CFM, SCFM, ACFM, etc., ALL refer to "the
volume of air that is compressed each minute and it is measured on the
_inlet_ side of the compressor." The "S" or "A" prefixes simply further
specify the temp and humidity of this inlet air.
