WebMay 17, 2024 · Fan Law 1: CFM is directly proportional to RPM. Formula: CFM2 = CFM1 X (RPM2 ÷ RPM1) or RPM2 = RPM1 X (CFM2 ÷ CFM1) What it means: As you increase fan RPM, CFM increases at a 1:1 ratio. So if you need to increase CFM by 10%, your RPM has to increase by 10%. Since it is a 1:1 ratio, we can interchange RPM for CFM in Fan Laws … Webbackward curved fan. Forward curved fans operate at lower speeds (typically 900-1400 rpm) and pressures compared to its backward curved counterpart.
