Static Pressure Fans Vs High Air Flow

Static pressure fans vs high air flow.

Static pressure optimized fans made to push the air harder through small spaces. The 3 points depict possible scenarios where the fan will perform. And when static pressure increases air flow decreases. Static pressure fans feature large blades fewer flat blades and small gap between the body and the fan blade which holds them together.

It can be expressed in these terms. What fan should you use. As you can see air flow and static pressure have a negative correlation. When air flow increases static pressure decreases.

Specifically i will be using corsair s sp120 and af120 models as these are very popular fans and have clearly defined characteristics sp for static pressure af for airflow. With static pressure fans vs airflow fans the fan blade structure is the main difference between these types of fans. For mechanical ventilation systems the fans create positive static pressure to move air through a given system. Static pressure is used to evaluate the amount of impact various ventilation system components have on the airflow path within a given system.

So there are two situations where you might think of choosing between a static pressure fan and an air. Most manufacturers performance charts are based on fan static pressure. Fan total pressure is the pressure differential between the inlet and the outlet of the fan. Static pressure fans come with wider blades but the gaps between the main difference has a direct connection with how the fans are optimized because the cooling system works differently.
