Fan (OpenBlocks)

The Fan is a block from the mod. This block can push entities within about 9 blocks in front of it, and a couple blocks to the sides of the front. As of version 1.2.6, the Fan requires a redstone signal to work.

The blowing effect cannot be blocked with any blocks. Fans can be put on top of each other to increase their force.

Unlike water, fans can push without automatically causing them to take damage and/or teleport.
