Popped ears is a wierd mechanic.

[Daitengu]

I can get behind fluctuations in pressure causing popped ear drums, but not constant slow pressure. I mean we got divers that deal with heavy water pressure fine so long as they take their time going up and down.

 

I say this as in every game I've played, my whole base became over 4k in pressure. Whole. Base. I have no way of dropping the pressure. heavy pressure vents you say? I need plastic. A thing weaker than metal for something supposedly stronger than the base version which is all metal.  I am always far from plastic research wise when I'm nearing 4k pressure. Besides that, no oil. Ever. Basically my games are over once my whole base hits 4k. The duplicated just vomit go 100% stress from the ear rupture and it never heals, because I can't reduce my base pressure ever.

 

Right now I just play with stress off so I can go on with my day and ignore pressure. Guess what, at 6k O2 pressure, whole base, including exploration tunnels, no oil.

 

I can literally do nothing but farm to keep my dups alive, and the pressure will kill their ears after a while, which stops them from doing anything else than camp the message tables or do their stressed out thing. That just makes no sense,

How did you manage to get the pressure so high? Oxygen producing stuff halts at 2k pressure. Basic vents don`t allow anything to pass above 2k. How do you get over 6k?

Are you mass producing O2 from terrariums? Then just getting rid of few would fix the overproduction.

Us it the CO2 piling up below the base causing pressure to grow? Carbon skimmers would deal with that really fast.

Do you have a geyser in your base area that rises the pressure? Sealing it off would help.

Digging up a large area to dump excess gas should help as well.

I never had an overpressure problem myself. I`m curious to see how your base looks like.

In my base, it's usually caused by weird gas exchange mechanics causing tons of CO2 to pool at suit checkpoints. Could be caused by waterfalls which seem to compress gas and move it up for some reason.

Well i never build suits next to my living zone so maybe that`s why i never got my base to overpressurize. Only had that happen in tight corridors that i didn`t manage at all.

I've never measured it, but I think pwater offgassing can overpressurize in a mixed oxygen environment.  I typically use suits exclusively so it's a bit of a sewer outside my living quarters.  I never bother cleaning polluted water, and I usually see pressures in the 3-4k range.

[Daitengu]

I build 6-8 terrariums(roughly 1 per dup) at the bottom of my base just above my waste water tank.That's it. As it's most efficient to clean up all the polluted O2 by having those two near. I STILL get the 'not enough O2 production' warning in the upper left hand corner, but I ignore it. I mean my whole base is O2, like bring up the gas map, the only Co2 is either out of base, or moving towards my terrariums.

 

The math of it just don't make sense to me. You would think the terrariums would stop producing O2 if there's no CO2 around, and never make more O2 than there is CO2. Maintaining them is at 5 priority, and I usually set everything else like harvesting the farms at 6 and power at 7 leaving  'do asap' and 'emergency' stuff to 8 and 9.

 

ps: It's impossible for me to move gases around since they are so pressurized. Which isn't how ventilation works. As it's pressure difference, not density from one end to the other that matters. I have to get those ice cacti from the glacier biome to cool my crops, because heat can't be moved around actively. That's with me air locking the hot zones outside of my base and moving all my heat producing machines to another area.  Because no oil for HP vents.

Well thats the best solucion to all his problems,

Living zones don't generate anywhere near enough gas for it to matter. Plus, they consume more than they generate, so they actually "pull" gas in.

Rockets, jet suits, petroleum generators - those are the biggest sources. They also don't check pressure.

If i remember correctly 1 terratium per dupe shouldn`t be enough to overpressurize the base. The terrariums produce a stabile amount of oxygen not based on the CO2. It`s like that beacause the amounts of CO2 dupes create aren`t realisitc so to keep them alive there needs to be more O2 produced. They don`t check how much oxygen there is around so might eventually cause overpressure but it shouldn`t be happening with such a small amount of them.

It`s actually super easy. Just dig a large room outside your base and conmnect it with the base via an airflow tile and the gas will move that way by itself. As long as the room isn`t in the slime biome (slime will emit polluted oxygen and fill the mined out area) then digging out a large area will mean you got a low pressure there. It`ll be easy to move gas any there. Even to pump it there if needed. Just make sure the area is pretty large.

Heat can be moved around it`s just sometimes tricky to do. Thermoregulators and aquatuners are great at moving heat around, especially in conjunction with radiant pipes. Just pump some cold water through radiant pipes in your farm and the temperature will drop instantly. Then use the aquatuner to cool the water back and the heat is moved  to wherever the aquatuner is in. Also works with thermoregulators but they are less effective (best use hydrogen as the cooling gas, just make sure it stays in pipes).

[SharraShimada]

Overpressured rooms are easy to make. 

For example: Build a vertical tube of 5 tiles width, 20 tiles high. Every 4 rows you place airflow tiles. Now pump in gas at the lower end, and watch pressure goes up at the upper end. It reaches insane pressure ratings at the top, while the bottom still lets in more gas via a normal gas-valve. 

Even easier, when you do this with hydrogen (goes up) and a bit of heavier gas, that covers the floor. So there will never >2k pressure for the valve, no matter how much is on the top of the tube.

Popped ears made exactly to force you deal with pressure.

People in this thread explained, how could it be possible, but the point is, if you have too much gas, just stop producing it. Unbreathable? Convert it, scrub it, transform into energy, dump it outside of your base. Are producers of gas supposed to stop when pressured? Check, what's wrong, and fix it. Removing whole preventing mechanic because you can't deal with the problem? Come on now. In worst case you can pump gas out into space. If you feel pressured, rush to the space.

 

I had 10t pressured hydrogen room once because there was 500g of mixed CO2 and pO2 at geyser. Those things happen.

[Daxterr]

I'm still confused what OP's problem was.

[ONIfreak]

There are two ways to drive oxygen to your base.

1. Vents ( and anything what is behind those vents)

2. Convert something to oxygen directly in base. 

 

2nd option has risk to make insane amount of gas in base cause it doesn't calculate it. So the easist solution is use option number 1. It doesn't matter what is behind vent - vent is your buffer to do not have issue with pressure.  It already has solution built in into its mechanic. Use it.
