But if you have a high traffic door, you're going to leak so much gas.Ī 3 door setup (back to back) is slightly better and doesn't require a pump because the middle door can possibly delete the gasĪ waterlock is probably the best use of an airlock. If you're assigning only 1 dupe passage by name via the door assignment, then you've minimize the problem. And you said you're not using automation? So technically when a dupe enters the airlock chamber of the 2 doors (the middle room), you need to have him wait until your pump removes the gas before opening the second door to let him pass otherwise, its possible for the gas to enter from one door and then exit through the second door when the dupe leaves. In real life, an airlock basically forces the person to be inside the airlock chamber until it decompresses before opening. So how exactly are you controlling the flow of dupes coming and going? At least in part because forcing the middle door closed breaks Dupe pathfinding.Ī 2 door setup with a pump in the middle. I've never built one of those 3-door airlock setups. If there's steam or something else hot on one side of the airlock you don't want to use them. The drawbacks of minipumps are that they require plastic and they've got a low overheat temperature. Two mini-pumps cover the entire area, and there's no slow progression through grams, milligrams, and micrograms of gas left. It has to empty that tile using the gas movement rules, and that can take quite some time before it gets to zero. There reason being that gas pumps and gas mini-pumps have a plus-shaped area of effect, so a 2x2 gas pump has one tile it can't empty directly. Generally this is fairly effective, and gas doesn't escape.Īn airlock with two mini-pumps is even better, since it uses less energy and is more effective at rapidly emptying the space. No automation, it just empties the interior to a vacuum. I generally prefer an airlock design that's just two doors and a gas pump.
