Of course, an engineer would choose a specific fan static pressure based on requirements for a specific application, but this reference states values in a very common range as found in typical VAV fan systems (Trane 2016).

In either case the energy input will always closely approximate that occurring when the filters are dirty and upon which the fan static pressure was determined.
Consider each of the quantities, specifically total fan pressure, fan velocity (dynamic) pressure, and fan static pressure, described in detail below.
The fan static pressure requirement for the heavy and extra heavy hoods is more than 2.
Fan energy calculation assumes the following fan static pressures: --Single wheel AHU (Scenarios A and C): Supply fan static pressure of 3.
AMCA Publication 201 defines the magnitude of SE as the difference in fan static pressure between a fan without SE and a fan with SE.
The second is to use fan total pressure instead of fan static pressure for fan selection.
Typical packaged HVAC systems are mainly employed in light commercial use including hotels, supermarket or retail stores, the compact arrangement of interior components introduces a non-ideal airflow pattern, resulting in both the fluctuation of the field fan static pressure and the difficulties installing the pressure sensors.
In either case, the energy input will always closely approximate that occurring when the filters are dirty and upon which the fan static pressure was determined.
Discharge ducts having a length of two to three times the fan impeller diameter were used to connect the fan to a nozzle chamber; this was employed to measure fan static pressure and flow rate.
