Oxygen upgrade
High Capacity Air Tank Guide
This page exists for players who can survive the first hour but still run out of oxygen during wreck scans, resource loops, and awkward exits.
Quick answer: High Capacity Air Tank is the bridge oxygen upgrade after the starter tank. This page covers the common High Capacity name and the Medium Air Tank wording until the live Fabricator label is settled. Exact oxygen value, prerequisite, and material count need an in-game check.

Route status
Recipe lead; oxygen value and cost need an in-game check.
In-game check
Check Fabricator row, prerequisite tank, oxygen value, and patch version.
Route and unlock plan
Oxygen-depth route after Standard Air Tank.
Step 1
Build Standard Air Tank first
High Capacity Air Tank is a follow-up goal, not the first oxygen decision.
Step 2
Use it to extend known routes
Upgrade oxygen before repeating a route that is already useful but too tight.
Step 3
Avoid blind deep pushes
More oxygen does not solve heat, predators, vehicle depth, or lost exits.
Step 4
Record the exact row
Current Fabricator text should decide prerequisite and material counts.
Player decisions
| Question | Status | Rule |
|---|---|---|
| When to craft | After starter oxygen | Upgrade when route time, not route knowledge, is the blocker. |
| Main value | Margin | It gives more room for scans, gathering, and exit mistakes. |
| Next step | Ultra High Capacity Air Tank or route tools | Choose the next upgrade based on whether depth, speed, or vehicle support is now blocking you. |
| What to verify | Recipe and value | Exact cost and oxygen value need a station check. |

Questions people ask
Is High Capacity Air Tank the same as Medium Air Tank?
This page uses the player-facing High Capacity Air Tank search name while noting the current-build recipe asset name Medium Air Tank. The exact in-game label should come from your current Fabricator screen.
When should I get High Capacity Air Tank?
After Standard Air Tank, when useful early routes are still too oxygen-tight.
Does High Capacity Air Tank solve depth?
No. It improves oxygen margin but does not solve vehicle depth, hazards, or route exits.
Are exact oxygen values confirmed?
Not on this page yet. Values need an in-game check before becoming fixed claims.
