How works Air vents?

[KhoghazJr]

Im planning to build a big Ship, but i have no idea how Air Vents work.

Air vent must be connect to a O2/H2 Generator with ice in to add oxygen in a room.


I recommend to do the needed Engineer tests in creative to know more.

I like to make manual airlocks so I will use button panel to "pressurize and depressurize"

Start by making a very small airlock and the rest will follow easily.


Airlock using a Balance tank to "pressurize and depressurize" and a O2/H2 Generator to refill when the Balance tank is empty

Engineer testing needed to know more and gain XP


Edit

Do not connect the "Balance O2 tank" to the O2/H2 Gen or to main conveyor line because you will full this "Balance tank" and you will not be able to "depressurize".

Oh! Manual airlocks =

If you want your ship to have an internal atmosphere, you'll need to start by making sure that all the rooms you want to use have no direct access to space, whether that's through the slatted window blocks (I forget what they're called), or even just a plain old hole.
Once you've got that taken care of, you're going to want to put double doors on all entrances that transition between atmosphere and vacuum, Basically, make airlocks on all external access points.
Internal doorways aren't so critical, but I like to try to design any combat ships in such a way that any rooms that can be potentially breached have airlocks at ALL openings, even ones deeper into the ship, but that's just my personal preference.
Anyways, once all your rooms are done, make sure that each one has a vent somewhere, and that the vent is connected to a central ventilation system. I like to make my ships with a central conveyor network that carries air and cargo and just be done with it.
As for the functionality of the vents themselves, pay close attention to the colors of the four little lights on them. Red means that the vent has no access to a cargo network, thus it can't vent out atmosphere into a room. Yellow means that the vent CAN expel air, but the room has a hole somewhere, and thus can't be fully pressurized. Green means that the room is airtight and the vent is pressurizing it. The last color is blue, but that's only used when vents are set to REMOVE atmosphere from a room. This is pretty useful when exiting a ship through the airlock, for example. Just place a vent set to depressurize between the doors, and you're set.
Keep in mind, though, that blue and green can have different numbers of lights lit, up to the maximum of 4. This indicates the atmospheric pressure of the room. If there's just one light, it means that the room is either a vacuum, or just has extremely low pressure. The more lights there are, the more air pressure is in the room, with all 4 being lit indicating that the room is fully pressurized.

Hope this helps!
