Static Pressure Fans Vs High Air Flow

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 vs high air flow.

For mechanical ventilation systems the fans create positive static pressure to move air through a given system. The more air you can move the more heat you can blow away. Much air flowing trough large spaces. Moves more air and become louder as it increases in speed the ideal fan would be a low rpm high cfm high static pressure.

Linus explains the difference between high airflow and static p. The difference is that static pressure fans have a blade design optimized for good air flow at higher back pressure air flow resistance and often at low back pressures will deliver less air flow than a fan optimized for that latter situation so if you put the flow versus back pressure lines for both designs on the same graph they cross over at some intermediate pressure. High flow high pressure. High flow low pressure.

Static pressure is used to evaluate the amount of impact various ventilation system components have on the airflow path within a given system. Cfm air flow. As there really isn t anything the air has to be pushed through but a mesh on the back of the case specifically designed for fans to blow air through a high flow would be your best bet to move as much air as possible through it. The 3 points depict possible scenarios where the fan will perform.

The more obstacles in the way of the air the more static pressure you want. When air flow increases static pressure decreases. 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.

One could also compare the matter to water or any other fluid going trough a wide versus narrow tube. The relationship between air flow and static pressure of a fan is shown in the graph above. All other components create. Static pressure fans are usually best for locations where they have to push air through a tight area such as a hard drive bay or radiator.

Air flow is the gaseous equivalent to the ampère and static pressure is the equivalent to the volt. Much air flowing through small er spaces. 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. And when static pressure increases air flow decreases.
