Airlocks

[Alex]

Is there anyway too keep gases apart from a room too another one?
I put like 4 airlocks next to each other and din t work.Hydrogen got on main base..,

Try using liquid air locks. They will either give your dupes wet feet or the sopping wet debuff which will give stress, but they block 100% of all gases, as long as the liquid remains in disturbed.

If you only care about separating gases and nothing else, CO2 pits will also work.

+1 for liquid lock.

If getting your dupes wet is a concern, and you have the resources, I've also seen folks set up one or two exo suit docks next to these to prevent wet dupes. (If the liquid lock is at your base exit, I put up as many docks as I have dupes, so everyone leaves in a suit).

If you want to go the non-liquid route, then you can use automation to make it a proper airlock. It'll be a room with mechanized airlocks on both sides and an atmo-sensor. While the atmo-sensor is sensing any gas, the doors are locked and a pump sends the air back to whichever side you want, then it unlocks when the room is pressurized. You can even use filters to choose which gasses go to which side of the room.

Sound cool and is not a bad ideea. I will do it in the late game but now i m going for the water one.

If you want to get fancy, another way to avoid wet feet/sopping wet debuffs is to use a waterfall as your airlock.

https://forums.kleientertainment.com/forums/topic/111471-oniversity-hydrodynamics-how-to-create-a-single-liquid-waterfall/

Use ladders or mesh tiles as the floor on both sides of the waterfall, and no floor directly inside the waterfall itself, so that dupes "jump" through the falls. No debuffs. And you can make the falls as tall as you like.

Takes up some space above and below the falls, and uses a small amount of electricity to pump the water (but a liquid valve keeps the cost low).

Do note that this is not entirely self-sustaining (you need the pump) and so it could eventually fail if you stop supplying power (though this would take a while, due to liquid built up in the pipe behind the valve).

That is a great solution to talk about but a terrible solution to actually implement using in-game tools.

It is not something a new player is going to be able to implement successfully.

For starters, it's going to be huge when the most naively designed liquid lock only takes up 5x4 tiles of space.

It is going to be incredibly slow because vacuuming out a huge room will take forever.

Automating everything will be a nightmare - you can't lock the doors (because locked doors will force dupes to find a different route, and thus break the airlock), you have to account for various problems (What if two dupes try to use the airlock at the same time? What if a dupe tries to use the airlock and then changes his mind?), etc.

The CO2 pit is the best one mentioned if you are talking about horizontal airlock going side to side.

[Dyex]

Also... never tried it and was just thinking, but a vertical airlock would probbly work easy too. (Put 2 doors vertical above the other with a ladder.)

If the doors open one at a time the gas trapped in the chamber should just rest ontop of each other and not move out of the room.

You could just remove the doors and do it with a vertical shaft and ladder too if the pressure and density does not change much.
Have the main oxygen main base at the bottem and the hydrogen at the top.

huh? All it uses is 2x2 for a pump, 1x1 for a sensor, and 2x2 for both airlocks. all in all, the open space is a 3x2, and it doesn't have to be depressurized from full after the first time. If you want to sort gasses then you can put the filters outside the chamber.

[Manxome]

Hydrogen lofts and CO2 pits will work to keep those gases contained under some circumstances even with no actual airlock, yes. You can also sort-of use pits for chlorine and natural gas, but if dupes ever go above them you will eventually need to pump out the CO2 that they exhale or it will gradually displace the lighter gases.

This only works if you are preserving the "natural" vertical ordering of the gases, and only if the pressure stays relatively constant (on both sides).

I don't think adding doors will make maintain the boundary under any circumstances where it wouldn't be maintained without them, although an extra airtight door can be a handy backup measure on ANY threshold to limit the damage if something goes wrong (e.g. if your liquid somehow boils or freezes).

Have you actually ever tried to build such kind of airlock? I guess not, otherwise you would know that you also need a duplicant checkpoint to make it to work properly without cancelling dupes errands.
