Representative estimates from filter manufacturer data sheets.
*
See manufacturers' specifications for pressure drop versus airflow data for specific filter media.
If the filter size that you are looking for is not contained in Table 7, refer to Table 8 for a comparison of Pressure Drop (initial/clean
resistance to airflow) versus Face Velocity for a variety of filter media types.
The following equations relate Face Velocity (FPM), Filter Area and Airflow (CFM):
Filter Face Velocity = Airflow / Filter Area
Minimum Filter Area = Rated System Airflow / Maximum Filter Face Velocity
