Why Fan Static Efficiency Matters. You can use the maximum static efficiency to determine the horsepower you need in your application. For example, if you have an industrial fan that can achieve 80% static efficiency and you’re trying to move 20,000 CFM through 10 inches WG of resistance, a 40 horsepower motor would get the job done.

This is the unit of measure which is used for various fan calculations. In order to calculate it, you must place one of the ends of a manometer where the fan inlet is.

This equation does not compensate for temperature, density or airflow charateristics of any particular fan or blower. Equation: P = (Q x p)/(229 x ) or. P = (Q x PF)/(33,000 x ) or. P = (Q x Pw
WhatsAppGet PriceGet A QuoteFor determining the airflow efficiency, the measured CFM is divided by the amount of energy (in Watts) that is used up when the fan is being operated at its maximum speed level. In such cases, the standard or minimum CFM to label a fan as an efficient one is considered to be 75.
