Standard O₂ Tank (Subnautica)

The Standard O2 Tank is a crafted piece of Equipment which boosts the player's Oxygen supply by 30 units for a total of 75 units. It is crafted at the Fabricator.

The player must equip the Standard O2 Tank in the tank slot of the Paperdoll UI in order to benefit from it. While not equipped, it takes up six slots (2&times;3) in the inventory.

It can be upgraded into the High Capacity O₂ Tank at the Fabricator, which can be further upgraded into the Lightweight High Capacity Tank or the Ultra High Capacity Tank at the Modification Station.

Equipping the O2 Tank will incur small swimming speed penalty. For more information, see: Swimming Speed.

Note that when an O2 tank of any kind is built, it defaults to being empty: it must be equipped in an atmosphere in order to fill it. This is important if the player intends to carry multiple tanks for deep diving without a vehicle.
