Singleblock Machines

Singleblock Machines consist of only one block. They serve very specific purposes and are always slower or less efficient than their multiblock equivalent, if one exists. They are also not easily upgradable; GregTech singleblocks have a fixed voltage tier and must be fully replaced when the time comes. However, they are still required to progress through the early game and some are even used throughout the entire game. Expect to switch to multiblocks in EV and IV when most of them become available.

The input/output (I/O) of items, fluids, and energy is nearly universal amongst GregTech singleblocks. There is always a face side which cannot insert/extract anything and an output side for automatically pushing items or fluids to an adjacent inventory. The remaining sides are valid locations for inputs, covers, or any additional outputs. Singleblocks also have a few configurable options, listed below.

Enable auto-output in the GUI of the machine.
Set the Programmed Circuit in the GUI of the machine. Necessary for some recipes.
Right-click with a wrench to change the direction of the output side. Sneak right-click to change the direction of the face side.
Right-click with a screwdriver to enable input from the output side. Very useful for automation with ME interfaces from AE2.
Sneak right-click with a screwdriver to enable the input filter which only allows items with a valid recipe into the machine.

Important:

Not all singleblock machines in GTNH are from GregTech. There are a select few from other mods (ie. Printing Press and Soul Binder) that do not follow any of the same rules or behavior. Visit their individual pages for more details.

Machines

The following are all the available singleblock machines in GTNH, organized by function. Most are available at every voltage tier from LV to UMV. A few are too complex to describe here and have their own individual pages. Singleblock Generators also have their own page. Exceeding the voltage tier of a recipe grants an imperfect overclock (2x speed for 4x power). Most machines only consume 1A of power although there are some exceptions: thermal centrifuge (2A), arc furnace (3A), crop synthesizer (16A), crop replicator (6A), pollution scrubber (2A), wireless charger (2A), and world accelerator (6A).
