Air Handling Unit Simple Specific Fan Power Calculations (GPG70)

Specific Fan Power or (SFP) 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), or how many Watts of power is needed to provide 1 litre of air.
This can be a useful way of measuring how efficient the ventilation system is. Estimated SFP are usually in the range of 0.5 to 4. The SFP can be used to check the efficiency of your system against comparative benchmarks.
