Static Pressure Fans Vs Airflow Fans

As you can see air flow and static pressure have a negative correlation.

Static pressure fans vs airflow fans.

When air flow increases static pressure decreases. Remember airflow fans are for the majority of uses where there s very little restricting the airflow. The relationship between air flow and static pressure of a fan is shown in the graph above. Af style fans have many thin blades 9 15 typically with a relatively steep angle.

This is a highly efficient design to move airflow volume with the least amount of fan blade noise. A matching of the system occurs when the airflow delivered by the fan at a given static pressure equals the static pressure resistance of the. 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. Linus explains the difference between high airflow and static p.

Airflow fans feature small blades more curved blades and decent gap between the body and the fan which holds them together. There s more to choosing the right pc fan than picking a size noise level and bearing type. With static pressure fans vs airflow fans the fan blade structure is the main difference between these types of fans. High static pressure fans are for situations where there s quite a lot of restriction in front.

Resistance is greater than the available static pressure of the fan the airflow cfm delivered by the fan decreases until the system pressures match. 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. And when static pressure increases air flow decreases.
