Make Ham Airlock like Mark Watney pls?

[Histekia]

For everyone who has watched "The Martian" or "Save Mark Watney" as some people call it, the next words will make a little more sense then for the people who didnt watched it.
So I put a Link of the Movie in here for everyone who wants to watch it and want to know what I actually mean.

In the Movie Mark blew up part of the HAB, or more the Door of it.
This Door was there to mantain atmospere and temperature between the inside and the outside.
Please correct me if I am wrong, but thats how I saw it.
 

Now I would like to have something like that for ONI, BUT, with the future that it wont let the gas escape from one room into another.
what I mean is something like to Doors connected with eachother by a room that everytime you enter you, of course take some gas with you from the room you came from.
Now in this little room that is connected by this 2 Doors, the gas will get pumped out and Gas from room 2, the one you want to enter will  get pumped in.
Then door number 2 will oped and you can finally enter the room you want.
 

This would need energy and Gas intake and outtake, I would even say 2 of them with a vent in the room and outside the room.

This way our Dupes could enter rooms filled with Natural Gas, Chlorine, Hydrogene and Carbon Dioxide, without mixing Gas or getting Gas you dont want to or need for growing Plants in a room or your Base at all.

What do you Guys think about it? I hope it was understandable.

You can do this number. Power draw is minimal.

Air filter should be set to Oxygen into your base and everything else to the other side.

Thanks for the picture, but i already had this tried out in my base, sadly the air pump was naver fast enought to pump out all the gas before my dupe opend up the next door, so gas was still coming from room 1 into room 2 thru the middle room

Gas pump is able to pump 10 kg/s so unless it was a super over-pressurised area there shouldn't be any problem with the setup. It'd probably help if the room with air pump was exactly the size of the air pump, so that no air can pass through without being sucked in.

Actually gas system is rated at 1kg/s not 10 like liquid system.

My bad.

I need it indeed in overpressurised rooms, like when I enclose chlorine geysir to hold in the gas so i can built a farm there without having the problem everytime I enter chlorine gets into my base, same goes with natural gas geysir

Gas pumps only average 500g/s at max capacity, though gas pipes can hold 1kg. Liquid pumps do supply the whole 10kg a liquid pipe can hold, however.

Regarding the topic at hand there are numerous methods people have employed to keep out foreign gasses from their base. I have started using the 4x4 room with pump setup now that we have heavy pressure vents. I will also use what are called waterlocks created using a water filled bowl to keep gasses from mingling.  Also can put 3 or more mechanized doors right next to each other, though this results in some gas being destroyed.

Do you mean in this case your airlock is 4x4 with just one pump in it? Won't that cause quite a lot of power draw every time someone goes through due to how slow gas diffusion is?

Airlocks = naptha = no energy.

The pump occupies the whole chamber so it only takes about 10ish seconds on standard speed per transit. I tend to use them more to create vacuum insulated doors to thermally isolated rooms. I still use waterlocks for access to my natural gas production area, but I use it in conjunction with exosuits to prevent popped eardrums and sopping wet debuff. I run my refineries in there as well as harvest coal after the hatches each the fertilizer.

I did use a pump airlock for my chlorine storage room which has reasonably frequent access as a bit of an experiment because I wanted preserve gasses on both sides of the airlock. It actually seems to do a reasonably good job. The energy drain doesn't seem substantial. I right it is hooked up along with a base pump to filter the CO2 and Chlorine out of the floor of my base to a couple of coal generators whose primary purpose is to keep my slickers warm in the face of very cold CO2 coming from my petrol plant. So 3 pumps 4 filters and a spaceheater are powered by what ends up being just a single coal generator. I've others setup but they batteries don't tend to get low enough for them to get fed.

Ah, I think I misinterpreted your "4x4" to mean a 4x4 inside area (which would need 4 pumps to cover completely, or quite a long time of waiting for one pump to vacuum it) rather than 4x4 including the walls. Yeah the 4x4 (2x2 inside) airlocks work well if there's no big pressure difference between the two sides.

[The Plum Gate]

I usually OP my airlocks, so that outside gasses are pushed out rather than in.

Not misinterpreted. Just wrong. Yes, I meant 2x2 or 4 tiles in size. I guess I thought 4 tiles and my brain output 4x4 by mistake.

Sorry for the confusion.

A single pump is actually only 500 g/s even though a pipe can move 1 kg/s.

On-topic: whether it's intended is debatable, but right now the best thing to do for airlocks is a liquid lock. The best kind of liquid lock is a naphtha lock because of the extremely high viscosity.

You can try the setup Tobruk pictured but put the O2 vent inside the airlock, that could pressurize your lock and push the foreign gaz outside.

Naphta is a bit late game so you should find a solution earlier I think.
