Fan is a rotational block added by PolyFactory. It can be placed in any direction, similar to a dropper. When connected and powered with rotational force, it will push any entity (including the player) in direction it's facing with force proportional to distance from the fan and the speed it's rotating. By using the Wrench, it can be rotated or set to "reverse" mode, which makes it pull entities instead.
