• ### Recalculate Filter Pressure Drops At Higher Airflows

2012-5-2 · So the pressure drop of the filter at 1200 CFM will equal just under .19-in. w.c. of pressure. Thats a 44 increase over the filter pressure drop at 1000 CFM. Notice that airflow increased 20 but the filter pressure drop increased 44. Thats what fan law two demonstrates. Pressure increases at the square of airflow.
