Oxygen pump

Oxygen pump

A small wall-mounted unit that releases oxygen into the surrounding room, allowing enclosed areas to repressurize in space. Essential for long stays in orbit

The oxygen pump is a constructable building device that can be used to lower the vacuum in a room, making it safe for habitation. It requires power to operate.

Acquisition[edit]

Oxygen pumps can be constructed once the Orbital tech research project has been completed. Each requires Steel 100 Steel, Component 2 Components, 2,000 ticks (33.33 secs) of work modified by the construction speed of the builder, and a construction skill of 6.

Summary[edit]

Every 250 ticks (4.17 secs), a powered oxygen pump lowers the vacuum percentage of its current room. The room must be enclosed by airtight structures and roofed. It changes the vacuum percentage at a base rate of −1% per second per 100 tiles, scaling proportionally to the number of tiles enclosed; for instance, a room with 25 tiles will reduce the vacuum percentage by −4% per second, while a room with 200 tiles will drop by −0.5% per second. Multiple oxygen sources may be required to pressurize especially large rooms.

Oxygen pumps in operation are completely binary, having two states of power consumption: high and low.

  • High: An oxygen pump that is actively pressurizing a room is in the high power state and consumes 150 W. It will stay in this state so long as the room's vacuum percentage is above 0%.
  • Low: If a room's vacuum percentage is at 0%, an oxygen pump will switch to this state and cease function unless the room becomes depressurized again. Power consumption is reduced to a modest 15 W. Oxygen pumps will also enter this state if placed in a position that can never be pressurized (i.e. built outdoors or in a space that is not airtight).

Note that oxygen pumps do not change the temperature of the rooms they are in; even once fully pressurized, a room will still be dangerously cold unless warmed to habitable temperatures through the use of heaters, campfires, and so on.

Oxygen pumps can be uninstalled and freely moved as needed.

Analysis[edit]

Oxygen pumps are the most accessible method of pressurizing rooms. While archean trees and life support units both passively reduce vacuum around themselves at no cost, both of them are restricted to specific locations and cannot be moved, meaning that new constructions and especially gravships must have oxygen pumps built to keep them breathable unless every pawn aboard is fully vacuum resistant.
