We are often asked for the specific fan power (SFP) for a given fan. This is usually given at duty point, and so you would need to know the design airflow and system pressure for your application.
If you have the design duty, then you can try entering this on our Fan Selection Program, then use the filters to tailor your fan selection, and as you will see, the selection program will give you the specific fan power.
The fan selector will not contain older products, and where the information isn't within the fan selection program, you can obtain a rough guide by formula.
Specific Fan Power (SFP) = watts/ litres per second
