Static Pressure Fans Vs High Air Flow

When air flow increases static pressure decreases.

Static pressure fans vs high air flow.

What fan should you use. So there are two situations where you might think of choosing between a static pressure fan and an air. Fan total pressure is the pressure differential between the inlet and the outlet of the fan. As you can see air flow and static pressure have a negative correlation.

High airflow fans simply push as much air as possible while static pressure fans are specifically designed to tackle installations with heightened impedance and resistance. 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. 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. All other components create.

Most manufacturers performance charts are based on fan static pressure. And when static pressure increases air flow decreases. A fan performance spec is given as a fan total pressure or a fan static pressure which can handle a certain flow rate. With static pressure fans vs airflow fans the fan blade structure is the main difference between these types of fans.

It can be expressed in these terms. Static pressure optimized fans made to push the air harder through small spaces. The 3 points depict possible scenarios where the fan will perform. Static pressure is used to evaluate the amount of impact various ventilation system components have on the airflow path within a given system.
