Codex Processing Air Separator
The Air Separator splits air into nitrogen, oxygen and argon. It needs nothing but energy: no items, no fluids, no water. It is a tier II machine and the source of the gases that the chemistry, the crystals and the Foundry's precision alloy need.
| Property | Value |
|---|---|
| Tier | 2 |
| Energy buffer | 100,000 E |
| Max. input | 8000 E/t |
| Input slots | 0 |
| Output slots | 0 |
| Upgrade slots | 3 |
| Recipe type | Air Separation |
The Air Separator window: 1 input slots, 2 progress, 5 energy and tank bars, 6 value, status and redstone lines, 7 buttons (redstone mode, telemetry, codex).
Give the Air Separator energy and it works: one run after the other, each filling its three gas tanks. It has no input slots; the air is everywhere.
| In | Out | E/t | Ticks |
|---|---|---|---|
| – | 780 mB Nitrogen, 210 mB Oxygen, 10 mB Argon | 400 | 100 |
The three gases come out in the ratio of real air, 78 : 21 : 1. Each gas goes into the tank that already holds it, or into an empty one.
Important
Pipe all three gases away
A run only finishes when all three products fit. Nitrogen fills its tank first; when it is full, the machine stops, even if you only wanted the argon. Pipe every gas away, or store the surplus in 
Gas Tanks.
The Air Separator takes energy on every side, from a Pipster cable, a generator next to it or any FE or Team Reborn Energy source. When the buffer holds less than one tick of the current run, the run waits and keeps its progress.
The three upgrade slots at the right edge take one kind each:
| Upgrade | Up to | Effect per upgrade |
|---|---|---|
 Speed Upgrade
|
2 | half the time, 2.8 times the power |
 Efficiency Upgrade
|
3 | 0.85 times the power |
 Parallel Upgrade
|
2 | 2, then 4 copies per run, 1.25 times the power per doubling on top |
Upgrades count from the next run. The buffer and the maximum input grow by the same factor as the power. A parallel run only starts as many copies as the gas tanks have room for.
- Gas pipes can drain all three tanks from every side; nothing can be put in.
- Upgrades can be inserted by pipes and hoppers; each slot takes only its own upgrade.
- When a tank is full, the finished run waits until there is room.
The R button in the top right corner switches the redstone mode: always runs, runs with a signal, or runs without a signal. Since the Air Separator always has its "input", redstone is the way to switch it off.
| Status | Meaning |
|---|---|
| Running | A run is in progress. |
| Waiting for energy | The buffer is too low; the progress is kept. |
| Output full – take the products out | The gases of the finished run do not fit. |
| Paused by redstone | The redstone mode stops the machine. A Grid Monitor that pauses machines shows the same text. |
The Air Separator needs components: a 
Machine Frame and two 
Copper Coils, with steel plates, glass and redstone.

When you break it, it keeps its gases, its energy and its redstone mode; the upgrades drop.
While it runs, the fan on top turns, frost flakes drift down at the front, a deep hum sounds now and then, and the machine gives off a little light.
Tip
What the gases are for Nitrogen becomes ammonia and liquid nitrogen in the Chemical Reactor. Oxygen makes nitric acid and quartz. Argon protects growing crystals in the Crystallizer and the precision alloy in the Foundry.
