Greenhouse air filtering now that filters run out

[Zeff]

Hi all,

Looking for ideas... I'm playing a new game on mars and I've just built the oxygen and c02 portions of a fully automated gas plant, cooling, displays that go colours when tanks are getting full and filters are running low, it only runs filter units when theres gas to be taken out of the cooled buffer tank etc... very proud of it

Now, I was going to just have another filter unit on my greenhouse that filters c02, feeds that back into the greenhouse and sends anything else off to the cooling input however, I've realised that filter will be running out all the time because it'll be recirculating c02 constantly.

How are other people doing this nowadays, any clever methods anyone can recommend?

My only other thought is maybe I'll just filter oxygen, pass the unfiltered back into the greenhouse but then over time the pollutants will build up from entering via the airlock. So if I did that, is there anyway to setup airlock so it dumps any atmospheric air before filling with air from the greenhouse?

Appreciate any ideas thanks

You could use the advanced airlock circuit board. It's built specifically for preventing atmospheres from mixing as you describe.

The other thing you can do is filter oxygen when the level gets too high and send that back to your main base tanks. Then have a filter unit to catch pollutants and volatiles then feed the remaining gas to the greenhouse.

Oh so thats what the advanced airlock control does? I haven't been able to find any info about it on the web, so I haven't used it. I guess I'll have to take a look thanks!

And yeah with that I guess I'll be able to just filter oxygen back to the plant that way filter only run out as fast as plants using c02, nice.

Thanks!

Just make heavy duty filters, it will last way way longer. If you can't make it, for now just use normal filters and find the material to make it.

Also, if you don't want to burn your filter unnecessary while cooling your air, then make a pipe with tons of radiator on it, fill it up with tons of X and use it to cool your air. Make sure there are both radiator outside and inside. Alternatively, you can just let your air run directly into the pipe of radiator. Either will work, don't matters. This method though will require you to setup logic to control the pipe valve otherwise your room will be too cold for growth.

Thanks yeah will upgrade to better filters, but even then still want them to last as long as possible.

This isn't really about cooling, its about keeping c02 while actually not having to spend energy reheating totally fresh air as much as possible :)
