A fan doesn't know whether it's pushing air into a volume or pulling it out. A fan just creates a pressure differential; in conjunction with any existing pressure difference, such as one created by an intake fan, the differential results in airflow. Some fans are better suited to moving the most air across a small differential, that's an "airflow" or free flow fan. Some are better at dealing with larger differentials without stalling, that's the static pressure fan.Just wondering if there is a fan design that is more optimally suited to exhausting air rather than pushing air? Kind of like the opposite of static pressure?
yes and yes, depending on the case. if its exhaust spot has a lot of material to move through a sp is best, if its wide open af is best. sp helps move the air through restrictions, af moves more air.Some fans, like the Noiseblocker NB eLoop create channels of air, whereas others spread the air out more. I wonder if that is the difference between static pressure and air flow fans, and whether either is more suited to being an exhaust fan?
