Air vent help

[Soarinrainbow]

Hi, I'm building a ship in creative mode. To pressurize a room, I made a simple setup of an O2 generator, attached to an O2 tank, attached to an air vent into the room. However, this air vent is for an airlock, so I want it to be able to depressurize a room as well.

When I set pressurize on, the air vent goes up to 4 green bars and works fine. But when I try to depressurize, it doesn't go down to 1 blue bar, it stays at 4 blue bars and doesn't depressurize.
I've tried it with multiple tanks to see if not enough room for the O2 was the issue, but it still happens. Thoughts?

Uh, I'm sure the video might help a bit, but I was sort of hoping for a written explanation. This is because the setup I described actually used to work for me; now it doesn't.

In creative, with a H2/O2 generator and oxygen tanks, it tends to fill them up completely. Basically, there is no room left to de-pressurize the airlock. In survival, if theres space in the tanks, it should work. I believe that is why.

Oh right. I tried that, and it actually didn't work. Sorry for wasting time, I'd just like to get this resolved.

Basically, you need to setup your O2 tanks such that you have one that is closest to the oxygen generator that is set to auto-refil, and to hoard. Then have another O2 tank connected to the same network that has both these disabled. The generator will fill the first tank and stop, leaving the second tank mostly empty. Once the first tank is filled, turn off your O2 generator or else you will keep filling your storage back up every time you pressurize the room, only for the secondary tank to fill when you depressurize. The point of a lossless or almost-lossless system is that you don't ened to keep pumping new oxygen into it.

For spaces with an interior volume larger than 3000 blocks inside (30x20x5) you'll want additional O2 tanks for servicing that room. For cases larger than that, or larger airlocks, you'll want to have a non-connected system comprised of just O2 tanks set to draw from an airlock to exhaust back into the room.

This is so far the correct answer, thanks! Although how would I be able to account for the additonal small amount of o2 constantly used up by the player's suit when in the room?

Alright, I know it's been a while, and I'm working on a new spaceship. I've incorporated the system you described to work with the ship's airlock. The pattern is: O2 generator, tank with stockpile and auto-fill, turn off generator, add default tank, connect to...to pre-existing air vent? Can the new tank do its thing when attached to an air vent that's already there? Or do I have to add the vent after the tanks? Because right now, I'm afraid the problem is still happening. If you have any solution, that's fine. Thanks.
