Optimal pressure for humans is 101.3 kPa. Due to the minimum of 16 kPa of O2, the pressure of 101.3 kPa cannot be changed too much without the situation becoming excessively lethal. Under 16% oxygen? You start dying. Under 90 kPa due to fire from a while ago? You start dying. Be mindful of this.

It's about time we stop with the theory and get down to business. The two machines at the top can dispense infinite pipes, and your wrench can disconnect and connect pipes. A [[T-Ray Scanner]] helps you look for damage to the system. You cannot disconnect pumps when they are on.


Due to the minimum of 16 kPa of O2, and the dangers of skirting that in slight reductions in pressure become excessively lethal (Under 16% oxygen? Under 90 kPa due to fire from a while ago? You start dying. 20% can go down to 80 kPa, at which point the air alarm is in red anyway).
Next up is a very simple step by step guide how to set up the Atmospherics pipe system to be (nearly) as efficient as possible. Note that this is only one style how to set up the pipes. There are many ways and they have their own pros and cons.

You cannot disconnect pumps when they are on.
* '''Pros and cons of this setup:


'''Things to make sure of:'''
::'''+''' In case of a toxin leak, waste gas will be sucked out quickly (if the area's air alarms are set to filter out the toxins).
* Use the O2 and N2 computers and set their vents to the maximum pressure (5066.25 kPa).
 
* Set all Gas Filter's to maximum pressure, and the 'unfiltered to mix' to max (4500 kPa) pressure.
::'''+''' In case of a breach, air will be poured out with a nice pace, helping you re-pressurize the room quicker after the breach is fixed.
* The waste pumps should all be at 4500 kPa pressure. Make sure they are pointed in the right direction.
 
* Basically, anything circled red in the guide set to it's maximum possible pressure.
::'''+''' In a room with the default 101.3 kPa atmospheric pressure, pipes < 303.9 kPa pressure can be unwrenched. With this setup, the grifflords cannot fuck up pipes in maint.
 
::'''-'''  In case of a breach, until the hole is fixed, you'll probably spend a small while fighting against the huge air current ("space wind") if you don't switch the vents off.
 
::'''-''' If you'd suddenly get a need to modify any pipes (quite unlikely), you'd need to lower the pressure to under 303.9 kPa, which could take a long time.
 
::'''-''' The station is more vulnerable for sabotage through [[Air alarm|air alarms]]. Someone can quite easily hack an air alarm somewhere and set the vents to push out air at maximum pressure, resulting in a shitty situation, because sucking out excessive air is slow.

If you are just trying to flood a gas like plasma, you can essentially do the basic set up with plasma instead of a N2/O2 mix.

* Air Filters on currently burning mixes can siphon out heated but PURE O2 and Plasma. Do the O2 first then the plasma, as there is less O2 in a fire and thus it functions faster. This (and H/E) allow you to reach really obscene temperatures.

* Any time chemistry sets off an air-affecting grenade (think welderfuel/ground plasma), the particles spread themselves as part of an airmix. This is bloody annoying, because though the Air Alarms pick them up as "High Concentration of Unknown Particles Detected", they are impossible to suck down to Atmos. Spacing the entire affected air is, as far as I know, the only real "cure". There is a viable way to clean this, if you can safely cordon off the area. Detonating a welding fuel tank usually cuts a hole to space on the tile beneath it, and thus if you set your internals on and wear a fire suit, is an highly unsafe but effective way of draining the air. It is also one of the few ways to destroy pipes which are at a high pressure and thus can be a useful emergency cut-off if there is plasma irrevocably linked to distribution. It does KO you, do damage, and can make a space tile, which means without internals and a fire suit it can kill you. Caution is advised.

* Any gas can displace O2, and less than ''16'' (also useful for optimizing internals) kPa of oxygen starts the Oxyloss. CO2 can be removed with the scrubbers, but to get rid of N2 simply apply some way of removing gas from the air and adding O2. My personal favorite is 2 air pumps, 3 connectors and a Air Filter and a canister: 1 pump draws in, goes through the connection and filters N2 into the canister, and the rest to the other pump, which expels it. Can also be used for N2O which is only sluggishly scrubbed otherwise.
