This article contains information that is updated for the latest Experimental Version of Subnautica: Below Zero. Players using stable mode may find this information inaccurate.


This article is about Pipes (Below Zero) in Below Zero. To see this subject's article on the Subnautica Wiki, click here.

Pipes and the Floating Air Pumps are crafted by using the Fabricator. They allow the player to pump Oxygen from the surface.

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.

Usage

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

  1. Place a Floating Air Pump above the water.
  2. Connect a Pipe to the Floating Air Pump. The Pipe will be shown at the end of the first Pipe.
  3. 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.
  4. If the player swims near the end of a Pipe, their air tank will automatically acquire oxygen.

Recipe

The blueprint for the Pipe is unlocked by crafting a Standard O₂ Tank. It is crafted in the Fabricator.

Databank Entry

Air Pumps
Air Pumps PDA Encyclopedia (BZ).png

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 floating air pump must have access to breathable air, and be floating on the water's surface
- Pumps must be connected to a pipe chain to function

Source: Unlocked by default

Trivia

  • 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.
