What is static pressure on an AHU supplying Air with hepa filter

Question

Accepted Answer

Static pressure on an AHU supplying air with HEPA filter is the pressure exerted by the air on the walls of the ductwork and filter.

Static pressure is the force exerted by the air against the walls of the ductwork and filter.
It is measured in inches of water column (in. w.c.) or pascals (Pa).
Higher static pressure indicates more resistance in the system, which can affect airflow and efficiency.
HEPA filters typically have a higher pressure drop compared to standard filters, leading to increased static pressure.
Proper static pressure is crucial for the efficient operation of the AHU and filter system.
