Ultra High Capacity Air Tank Availability

Older item lists can include equipment that has a name and a recipe but is unavailable in the current release. A larger tank name alone is not a reason to spend time on a fragment search.

Quick answer: The Ultra High Capacity Air Tank is marked unpublished in PC build 128456. Use the available Standard Air Tank and High Capacity Air Tank recipes for your next oxygen upgrade.
