Static pressure vs cfm fan law

WebApr 16, 2024 · This is sort of a big deal since a fan selected for a certain cfm and static pressure are often capable of moving more air (cfm), just not the elevated static pressures that increase non-linearly with the cfm. Another reason that static pressure needs special consideration is that, as it increases, energy usage increases. WebAirflow indicates the volume of air that a fan can move per unit of time, and static …
