===[[File:vent.png]]Unary Vent===

The vent will pump gas into the room it is in, depending on the air alarm settings of the room. The air alarm has two settings to worry about, External, or Internal. External works by making the vent pump gas from its connected pipenet into the room until the room, or more accurately, the tile, matches the pressure that is set. The max pressure you can configure for External is 5066 kPa, and it slows down when approaching the set limit, as pressure pumps do. Internal works by pumping gas into the room from the pipenet until the pressure set matches the pressure in the connected pipenet. Examples: a vent set to External 200 will pump gas into the room until it is 200 kPa. A vent set to Internal 300 will pump gas into the room until the connected pipenet's pressure is 300 kPa, regardless of room pressure. As such, Internal 0 will always pump at full strength. This same effect can be achieved by turning off both External and Internal. The vent has a maximum speed it can pump at, even when extremely pressurised.

It should be noted that the vent can be made to suck gas as well, like the Scrubber below, when set to do so in the air alarm. It should also be noted that it does so '''faster''' than the scrubber, but it can not suck in gases in a 3x3, which means it loses in speed when the extra area matters and the pressure is low. The vent has no pressure limit when sucking in gas, which can be used to hilarious ends.
