Standard O₂ Tank (Subnautica)

This article is about the Standard O₂ Tank. You may be looking for the High Capacity O₂ Tank, Lightweight High Capacity Tank or Ultra High Capacity Tank.

Carrying multiple oxygen tanks will increase your survivable exposure time in hostile environments.

― PDA, Dialogue

The Standard O₂ Tank is a crafted piece of Equipment which boosts the player's Oxygen supply by 30 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 (2x3) 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 or carrying any O₂ Tank will incur a swimming speed penalty. For more information, see: Swimming Speed.
