From Wikipedia

Specific fan power (SFP) is a parameter that quantifies the energy-efficiency of fan air-movement systems. It is a measure of the electric power that is needed to drive a fan (or collection of fans), relative to the amount of air that is circulated through the fan(s). It is not constant for a given fan, but changes with both air flow rate and fan pressure rise.
