Stationeers – Simple Gas Filtration System

A simple guide on how to filter gases that isn’t a total pain.

Filtration

I spent a lot of time building a filtration system with many paths. Each path needed to be emptied before I could change the gas going into the tank. Then, I figured out a better way to do it.

The solution is easy to use and can be made bigger to handle more gases. You need one filtration machine per gas, a filter for each gas, and a storage container for each gas. You also need a way to get rid of the extra waste, like a vent or another storage container. Power is also needed.

Steps to create:

• Pipe in the gas you want to filter, can be any combination/amount of gases you want
• Place down a filtration machine for each of the gases you want to filter out, keeping at least two spaces between them for power/piping, put a single filter inside each of them
• Pipe the unfiltered input into the first filtration machine and then pipe the filtered output to whatever storage method you want, connect power
• Repeat the last step for every additional machine but instead of using the unfiltered input use the waste side of the filtration machine (side with the power switch)
• Pipe the waste side of the final filtration machine to a passive vent in space or store it for later

That’s it!

There are a ton of ways to improve on the system, like by adding back pressure regulators that could keep the storage from overpressurizing by venting excess into the waste pipe, but this should be enough to get started and then you can customize it to be your own. Enjoy!
