Encased Fan

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.

Usage

Power Generation

When an Encased Fan is placed facedown directly over a heat source such as (Fire, Lava, Magma Block, active Blaze Burner, Soul Campfire, or a Campfire) and powered by Redstone, it will provide 64 units of Kinetic Stress at 4 RPM.

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.

Entity Push distance
(based on item push distance)

Speed in RPM	Distance in blocks
1-12 RPM	4 blocks
16-28 RPM	5 blocks
32 RPM	6 blocks
48 RPM	7 blocks
64 RPM	8 blocks
80 RPM	9 blocks
96 RPM	10 blocks
112 RPM	11 blocks
128 RPM	12 blocks
192 RPM	16 blocks
256 RPM	20 blocks

Bulk Item Processing

When the air stream of an Encased Fan passes through certain blocks, the air stream downstream will apply the respective processing to items.

• Washing:
  •  Water
• Smoking:
  •  Fire
  •  Campfire
  •  Empty Blaze Burner lit with Flint and Steel
  •  Blaze Burner (smouldering)
• Blasting:
  •  Lava
  •  Blaze Burner (Fueled)
• Haunting:
  •  Soul Fire
  •  Soul Campfire
  •  Empty Blaze Burner lit with Flint and Steel and right clicked with Soul Sand or Soul Soil.

The respective 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.

Mob Interaction

When the player or a mob steps into a Bulk Processing stream, various effects may be applied.

• Smoking sets the entity on fire and deals 2 or 3 damage depending on Difficulty.
• Blasting sets the entity on fire and deals 3, 4, or 6 damage depending on Difficulty.
• Washing streams extinguish entities on fire and deal 2 damage to Endermen, Blazes, and Snow Golems.
• Haunting streams apply Slowness II and Blindness.

(SPOILER WARNING)

Horses can be Haunted, resulting in a Skeleton Horse with the same stats. Beware that Haunting an untamed horse may result in an untameable Skeleton Horse.

Bulk Item Processing Speed

All forms of Bulk Processing (Smoking, Blasting, Haunting, 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 (multiply by amount of fans)
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.
• Bulk Washing will apply any recipe listed below:
