Portable Tank

From Unofficial Stationeers Wiki

Portable Tank
Created With Hydraulic Pipe Bender
Cost 20g Iron
Max Pressure 10135 kPa
Volume 790 L


The Portable Tank is used to store gasses. It has a higher volume than the Gas Canister or Gas Canister (Smart).

The "standard pressure" when spawned is defined as 8106 kPa, or 80 Earth Atmospheres. The maximum pressure for the tank is 10.132 MPa, or 100 atmospheres. Overpressurizing the tank will cause it to explode. Once the maximum pressure is reached the tank starts taking damage until it bursts. This allows the Portable Tank to exceed the pressure rating temporarily.


The Portable Tank can be connected/disconnected to pipe networks using a Tank Connector, by placing the tank on the connector and then interacting with it using a Wrench. It can also be connected (and disconnected) to the Rover and Lander, with one Portable Tank of Oxygen normally spawning on the lander.

The front of the tank features a striped area where a Gas Canister or Gas Canister (Smart) can be inserted for refilling (equalizing the pressure in both canisters). There is also a pressure regulator valve on the top of the tank that can be used to vent the tank to atmosphere (or into a sealed room). Note that this valve does not need to be opened when connected to a Tank Connector, but the setting of the valve remains persistent between connection and disconnection.


  • If you need higher pressure (and thus higher capacity) canisters, consider using Gas Canister (Smart), which have visible display of tank pressure and a pressure capacity twice that of the standard Gas Canister.
  • Default colour marking in Stationeers:
Blue H2O (Water)
Green N2 (Nitrogen)
N2O (Nitrous Oxide)
Grey CO2 (Carbon Dioxide)
X (Pollutant)
Orange Fuel (H2 66% + O2 34%)
Red H2 (Hydrogen / Volatiles)
White O2 (Oxygen)
Air (as defined in-game as O2 25% + N2 75%)
Yellow Stock colour after manufacturing (Empty)
  • Other common (player) colour markings in Stationeers:
Black X (Pollutant, replacing Grey)
Khaki Air (as defined in-game as O2 25% + N2 75%, replacing White)
Air 20/80 (Earth Standard, less 1% Argon)
Nitrox 35/65 (alternate breathable mixture)
Pink Hydroponic Air (any breathable mix with also including >2% CO2)
Purple Exhaust Gas (any High Pressure / Temperature mix including x and CO2)
Brown Body-specific Atmospheric Gas
Yellow Waste / Exhaled Gas (per default Waste Canister)
