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 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 (2×3) 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 a 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.
