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, distance from fan to a wall, 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.

Movement

Fans will move an entity direction it's facing with force proportional to distance from the fan, using this formula, where d is the distance from the fan to the entity, l is the length between the fan and the closest fan-preventing block, s is the rotation speed, and m is the movement multiplier:

push = max(s * (l - d) / (l + 1) * 0.98 ^ l * m, 0);

Obtaining

It can be crafted using Steel Plate, Axle, Iron Ingot and Iron Bars.
