The Vital Apparatus Vent.

The Aperture Science Vital Apparatus Vent is the final part of a system that distributes Weighted Storage Cubes into the Enrichment Center Test Chambers.


DescriptionEdit

Located on ceilings, they are connected to the Pipe Network which uses varying air pressure to move Weighted Storage Cubes through the facility. It automatically delivers a new cube each time Chell destroys one. In Test Chamber 16, a damaged vent is randomly opening and closing, allowing a large pile of cubes to build up below it. It was probably intentionally sabotaged by Doug Rattmann, explaining the presence of a radio, a set of tools and a coffee mug, as well as a black hand-print on the wall. The Pneumatic Diversity Vent, used to transport any object, is a more complex variant.
