Pressurized Air Tank

The Pressurized Air Tank, previously known as the Internal Oxidizer Tank, is an upgrade added by Immersive Engineering for the Mining Drill. Like all upgrades, it's applied in the Engineer's Workbench.

The Pressurized Air Tank allows the Mining Drill to work underwater. More than that, it allows the Mining Drill to mine without the slowdown that usually occurs when mining in water.
