The Encased Fan is a mechanical component that can create air streams and generate power. Its air streams are used for moving entities or for Bulk Washing, Bulk Blasting, and Bulk Smoking.
The Encased Fan connects to other rotational components from the back.
This setup is tied with a Windmill Bearing attached to a single block of Wool as the most compact power source available in Survival mode.
Pushing and Pulling Entities
When powered by Rotational Force, an Encased Fan creates an air stream that extends several blocks in front of it. This air stream pushes entities away from the fan or pulls entities towards it depending on the direction of the rotation that the fan receives. Powering an Encased Fan with faster rotational force will cause its air stream to be stronger and faster.
Items will always be pushed, but mobs or players won't be pushed until the Fan is running at least 4 rpm. The maximum push and pull distance can be changed in the Config.

Bulk Item Processing
When the air stream of an Encased Fan passes through Lava, Fire, or Water, the air stream downstream will apply to items Bulk Blasting, Bulk Smoking, and Bulk Washing recipes, respectively. These recipes are applied to item entities when they sit in the air stream, whether they are in the world, on a Mechanical Belt, or on a Depot. These recipes can be applied to multiple items at once.
Bulk Item Processing Speed
All forms of Bulk Processing (Smoking, Blasting, and Washing) process items at the same speeds. However, different stack sizes take a different amount of time to process, as listed below:
Bulk Item Processing Speeds
Item count in a stack
Processing time
Maximum belt speed
1-16
7.5 seconds
3.2 RPM
17-32
15 seconds
1.6 RPM
33-48
22.5 seconds
1.06 RPM
49-64
30 seconds
0.8 RPM
Note that if a recipe's output is also a valid input for a different recipe (such as Cobblestone → Stone → Smooth Stone), the second recipe will start being processed immediately after the previous one is finished. Use Depots with filtered Brass Funnels, Mechanical Arms with filtered outputs, or Mechanical Belts set to the correct speed (as listed above).
Bulk Item Processing Recipes
Bulk Smoking will apply any recipe that can be applied in Smokers.
Bulk Blasting will apply any recipe that can be applied in Furnaces but not Smokers.
Warning: Passing incompatible items through Bulk Blasting will incinerate them.
