An accurate measurement of static presure is critical to proper fan selection however. Static pressure in fan systems is typically less than 2 SP, or 0.072 Psi. The amount of static pressure that the fan must overcome depends on the air velocity in the ductwork, the number of duct turns (and other resistive elements), and the duct length.

Higher static pressure means that the fan can even ventilate inside equipment with high mounting density. The maximum airflow is defined as the airflow when there are no obstructions on either the inlet or outlet sides of a fan. The maximum static pressure is the static pressure when the fan's outlet is completely blocked.
