Abstract: Various devices, systems, and methods are described herein that provide bi-directional, and even multi-directional airflow within fan systems. These fan systems can be utilized by devices such as datacenter switches to change from one direction of airflow (such as port side inlet) to another direction (such as port side exhaust). This can be done manually by having a multi-directional fan housed within an enclosure that provides access through a hatch door. The multi-directional fan can be removed and reoriented to a second direction, thus providing airflow with the same quality and pressure in multiple directions. Fan changes can also be automated through one or more interlocking rotational gears coupled to the fans within a housing, such that rotating one gear will rotate each of the fans within the housing, thus changing the direction of the airflow. By doing this, only one fan is needed to provide airflow in multiple directions.
