Static efficiency means the efficiency of a fan, based upon measurement of the difference between the stagnation pressure at the fan outlet and the stagnation pressure at the fan inlet minus the fan dynamic pressure corrected by the Mach factor;

Static efficiency means the overall static efficiency. It is the ratio between the nominal airflow multiplied with the static pressure rise of the fan (equal to the sum of pressure drops of all ventilations components, clean and dry, and the nominal external pressure) divided by the electrical power of the fan drive.
