An Oxygen Recycler.

Oxygen is a necessary resource, like Power, to running a space station. Oxygen is generated by Oxygen Recyclers in a Life Support room.

Any citizen or Raider on EVA will have only eight minutes' worth of oxygen in their spacesuit.


  • Each Oxygen Recycler provides just enough oxygen for three citizens. However, it is inadvisable to keep your oxygen level at capacity, as the saturation of each room will drop to ~70% and lower your citizens' Morale.
  • Construct one or two more recyclers than you need. This will keep your citizens happy and allow for some recyclers to be destroyed without your citizens running out of air.
