Duplicant Checkpoint Vacuum Chamber

[Neotuck]

how about this design? dupes can only move though it when there is a vacuum in the middle or the inner doors will be locked shut, the buffer has a 1s delay so dupes won't get trapped as they run though it.  The filter keeps the O2 in one room and CO2 in the other

Wait.... Isn't this what tubes was also meant to solve?

I'll test it tomorrow when I wake up; I think dupes might get stuck in that sometimes

first one works perfectly take a look if you want:

It'll break the moment you have big pressure differential (e.g. 20kg on one side vacuum on the other), especially when you build it in survival where dupes are leveled and move way faster than those doors can close.

The gas pump/floor switch logic does nothing useful. Leaving the pump on at all times works in exact same way. Removing the 2 tiles occupied by atmo switches speeds up the vacuuming process massively.

Like @Neotuck said pump between 2 doors does exactly the same thing without slowing down dupes. If you want insurance just chain 3 gas pumps in this way (it takes the same amount of space as your idea). I don't like his latest design though, because when the doors are closed to create the vacuum, it breaks move orders for dupes.

So you want to prevent gas transfer between 2 areas?

Do waterlocks stress your dupes?

Try this:

Notes:

Set buffers to 1 sec

Set atmo sensors to below 0

Have build this kind of vacuum door very usefull, but what's the point to have to atmo sensor? You can have only one so the pump made the vacuum faster (so less energy).

Also i discover something anoying when i made it, if check point run out of energy they don't work anymore and it's on position open very anoying cause without energy the pump don't make the vacuum and the vacuum airlock be useless

My preferred low-power solution is just a co2 trap with a 5 tile high ladder on each side, the co2 provides good temp isolation and fabulous airlock separation, even against high pressure. You can also do a hydrogen / oxygen ceiling trap in a similar way.

I find a pump surrounded by airlock plus gas filter also works really well, you can use 2 pumps with 3 airlock sandwich to go overkill. If you want temperature isolation just add 1 tile space inside, so 3 tile wide between airlock with a pump.

You can use smart battery and extra door  to block airlock if no power to run the pump.

Hmm, I just use the 2 horizontal locks in the midspace, if you are paranoid and your dupes have got very fast then you can do

 

l=l=l  and make sure of a perfect seal.  Doesnt even take power, or get the dupes wet.

but does delete gas
