How to release oxygen from oxygen tank

[JuiciestDreamer]

Title says it all. I have an oxygen tank that I filled to 50% for my airlock to pressurize and depressurize. But someone decided to not listen to my note and connected the oxygen tank to the rest of my station so the tank is now full and the airlock cannot depressurize. But I can't seem to drain some of the oxygen out.

Sadly they have not put any oxygen controls in when it comes to being able to push oxygen out of a specific tank. I have asked for it for months on their idea forum for more controls.

Best thing you can do is remove any conveyors from the tank that connect it to the main network, create a new sealed chamber with a vent on both sides. Connect the tank to this room and fill it with air, have the other vent feed into another tank with room and depressurize the room. You will, however, lose around 60% of the air by doing this for some reason. You might as well fill a hangar bay with air from the tank and then vent it to space as it would be quicker.

Anyway in future you should use an oxygen management script that controls when your generators and o2 farms turn on and off based on the oxygen tank levels instead of micromanaging them manually. They are available on the workshop, easy to set up and run. They will not fill the tanks past something like 85% and turn on the generators when the tanks dip below something like 20%. The one I use lets you change these values too.

add a standalone tank and vent to the room you want to drain, only put power to it and dont conveyor it, pretty much the only way to not waste O2 at that point

Can't you just turn off O2 generators, build a new O2 tank somewhere on the network, then set the new one to stockpile and the old one off stockpile? You can also just fill up a room and open a door a few times.
