A compactor is a machine that applies pressure to items to change their form. It can be used to automate storage crafting recipes, and to make metal plates and coins.


A placed compactor can be instantly picked up by dismantling it with a crescent hammer. Its configuration is preserved in the item. It can also be mined using a pickaxe, though this can be much slower.



A compactor is initially at the lowest tier (basic). It can be upgraded to higher tiers using upgrade kits and conversion kits.



When placed, a compactor faces the player. It can face any of the four cardinal directions, and can be rotated using a crescent hammer or similar.


When items are placed in a compactor’s input slot, the machine will start consuming Redstone Flux to process them. Every item requires a certain amount of energy to process. When enough energy has been consumed for an item, the input is consumed and the output is placed in the output slot.

The speed at which a compactor processes items depends on how much energy it can use per tick. This in turn depends on how much power is being supplied, and on the machine’s maximum power usage. A basic compactor has a maximum power usage of 20 RF/t. This can be increased by upgrading the machine to a higher tier, and by installing certain augments.

Input and output

Items can enter and exit a compactor through its sides. Every side of a compactor may correspond to its input slot, its output slot, or both at the same time.

A compactor can automatically transfer items out of any sides that directly correspond to its output slot. This is called auto-output. It can also transfer items from adjacent inventories into any sides that directly correspond to its input slot. This is called auto-input. Auto-output and auto-input occur whenever the machine finishes processing an item, or every 32 ticks (1.6 seconds) if the machine is inactive.

A basic compactor can automatically transfer up to 8 items at a time. This amount can be increased by upgrading the machine to a higher tier.

Which sides correspond to which slots and whether auto-output and auto-input are enabled can be configured using the Configuration tab in the machine’s GUI.

Redstone control

A compactor may be configured to respond to redstone signals. It can be in one of three modes:

Redstone control is disabled. The compactor works whenever possible. This is the default mode.
The compactor works when not powered. When powered, it stops working.
The compactor only works when powered.

The current mode can be set using the Redstone Control tab in the machine’s GUI.

When a compactor must stop working due to a redstone signal and is still processing an item, it will finish processing that item before stopping.


A compactor can have a signalum security lock installed to restrict who can access it.


A compactor’s configuration can be saved on a redprint to be copied to other compactors.


Compactors come in six tiers.

Tier Max. power usage Augment slots Max. items per auto-transfer
Basic 20 RF/t 0 8
Hardened 30 RF/t 1 16
Reinforced 40 RF/t 2 28
Signalum 50 RF/t 3 44
Resonant / Creative 60 RF/t 4 64


A compactor can have augments installed to improve certain properties or to change how it works. The amount of augments that can be installed depends on the machine’s tier. A basic compactor cannot be augmented.

Augments can be installed in the Augmentation tab in a compactor’s GUI.

Augment Installable in Description
Auxiliary Reception Coil Auxiliary Reception Coil Any machine Increases a machine's maximum power usage (speed). However, also increases the amount of energy required per operation. Can be installed multiple times.
Numismatic Press Numismatic Press Compactor A specialization that allows for a compactor to produce metal coins. The machine must be toggled into Mint mode.


A compactor can be in two modes, each with a different set of recipes: Storage and Press.

If a numismatic press is installed, the Mint mode is also available with the recipes added by the augment.


When in Storage mode, a compactor’s recipes are based on storage crafting recipes. These are any recipes that consist of 4 or 9 of a single ingredient, like the recipes of glowstone and blocks of iron.

Every storage recipe can be performed in a compactor for 400 RF.
