This is the formula for fan CFM: Cubic feet per minute, more commonly known as CFM is calculated by the following formula: air speed (feet per minute) X area (square feet)=CFM. Not everyone is going to take a look at CFM, but for those who do it is a helpful tool. In simpler words than that of the formula, it is the amount of air a fan moves. The amount of air depends on some other factors as well, such as the diameter and shape of the blades, speed at which the blades turn (revolutions per minute or rpm), horsepower (hp) of the motor, and overall fan design. These combined factors establish the air moving capacity of a fan. Fan capacity is measured... more
