To calculate CFM (Cubic Feet per Minute) for a dust collector, multiply the cross-sectional area of the duct (in square feet) by the desired air velocity (in feet per minute). The formula is: **CFM = Area × Velocity**. Typically, for dust collection, an air velocity of 3500–4000 FPM is recommended to keep dust particles suspended.
