Aperture Science Vital Apparatus Vent

"Weighted Storage Cube destroyed. Please proceed to the Aperture Science Vital Apparatus Vent for a replacement."

- GLaDOS

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

Overview

 * 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.

Behind the scenes
Early Portal 2 images confirm that the Vital Apparatus Vent will be featured in Portal 2, with an extremely improved design.
