The Base-attached Air Pump can be constructed using the Habitat Builder, which allows the player to pump Oxygen from a Seabase instead of the surface. This may be a more preferable choice for areas too deep to use the Floating Air Pump.
Note that the function of pipes and air pumps is not to supply a base with oxygen, but to create a location underwater where breathable air is accessible to the player. Pipes cannot supply a base with oxygen.
Pipes allow the player to create a network of interconnected Pipes with readily available Oxygen underwater.
The Base-attached Air Pump pumps Oxygen through Pipes from a Seabase without the need to place Pipes at the surface.
A Pipe must be connected to an Air Pump in order to carry oxygen. A player's Standard O₂ Tank will start filling once they swim near an active Pipe.
How to Use
- Place a Floating Air Pump above the water.
- Connect a Pipe to the Floating Air Pump. The Pipe will be shown at the end of the first Pipe.
- The Base-attached Air Pump can be placed on a Seabase to pump oxygen through Pipes without having to place Pipes at/from the water surface.
- If the player swims near the end of a Pipe, their air tank will automatically acquire oxygen.
Air pumps can be used to pipe breathable air to a remote location.
- The base-attached air pump can be built at a compatible habitat, and will source oxygen directly from the habitat's oxygen generator

- The Databank Entry image for the Floating Air Pump displays an incorrect representation of diatomic oxygen, showing it with five valence electrons on each oxygen atom and a single bond between the two, when there should only be four valence electrons on each and a double bond between the two oxygen atoms.
