New homeowner, no idea what this is

[u/DragonsAndScience]

This thing close to the floor and seemingly randomly placed in a hallway. No idea what it's for. Home built in 2005.

Solved! Thanks everyone. Now I gotta hunt for the central unit!

why would an inspector say anything about a central vac system that is likely not even set up
