How do i fill my O2 tank with additional air

[Down with Orrix]

Hey there, i'd like to make air to put into my oxygen tank. i currently have a pressurised room, the 3 initial machines (Autolathe, electronics printer and the pipe bender thing). My room has locker storage and ive made C02 and pollutant filters for the air scrubber so that i can breath with no problems.

My current issue is i dont know what to make to fill my oxygen tank since if i dont do this i'll die eventually, i still have around 3500 kPa though.

Also should i be trying to encourage a proper atmospheric mix rather than pure oxygen just as good (non explosive...) policy for when/if it does change in future? Welding in pure oxygen without dying seems funny although i have no idea how to even create a proper mix of air for the base

on new saves you are given an oxygen tank that you can refill your tank with. beyond that you have to find ice and melt it against an active vent that will suck it up through pipes and into filters to split the different gases.

Congratz, you used you spare oxygen to pressurize a unnessesairy base at this stage

Most people use that tank, (i do at least) like descriped by previous poster as spare oxygen, that buys time to build a foundation for you'r base, IE, melting chamber when you get your oxygen from, and other gasses, and power districbution.

TBH pressurizing a base is currently, well End game stuff, even though the game give most stuff to do so, its very low on priority.

using that spare tank for pressurizing, you robbed yourself of time to build a small room, with a vent in it, used the doors to enclose that room, and make piping and storage for the gasses.
although you can collect there in the open with an active vent, a specialized room is ofc much more efficient, and can handle bigger volumes faster.

I think best now, throw some oxide in your base, let it melt, let the scubber filter oxygen, put scrubber on tank connector, connect this to gas tank holder, insert cannister, profit of nice fresh oxygen.

n2/o2 mix helps currently mostly in controlling large volumes of air with heat dispersion.
100% oxygen is kinda explody, but if your into fireworks, its recommendable..
Its not needed for use in your suit, 100% oxygen is just fine, small room without heat sources, no problems either.
