Ahem.

You mean CFM. There's no square feet in cubic feet ;-)


No, he means SCFM

In many process applications there is a critical demand for a specific
minimum flow in terms of some base or reference pressure, temperature and
relative humidity. Many standards are used, the most common being the
Compressed Air & Gas Institute (CAGI) and the American Society of Mechanical
Engineers (ASME) standards, which are 14.7 PSIA, 68Deg. F and 36% relative
humidity. When you express your "Demand" in Standard CFM (SCFM), you are
saying that you want this compressor or blower to deliver this CFM even at
your worst case conditions.
