Aperture Science Pneumatic Diversity Vent

The Pneumatic Diversity Vent is a device used in the Aperture Science Enrichment Center several centuries after Portal, and slated to appear in Portal 2. Some sort of upgraded and open Vital Apparatus Vent, also connected to the Pipe Network, it distributes objects to Test Chambers.

Overview



 * The Pneumatic Diversity Vent produces strong suction at its end. This is to be used by Chell to her advantage in Portal 2: for instance, placing a portal under the tube and another under an unsuspecting Sentry Gun, the threat is immediately leeched upwards into the Vent and redirected elsewhere or eliminated. This concept can also be applied to a Test Chamber littered with objects: when Chell places the portal in the center of the mass, it creates a swirling vortex of debris, while they are all sent through the Vent. When used for such purposes, its end will be named "Non-Discriminatory Entrance Port".


 * The Passive Monitoring system ensures objects in the vent are identified, but never judged.


 * Any object sucked by a Pneumatic Diversity Vent can be sent to the so-called "Diversity Furnace", the possible nature of the orange glow seen in the Pipe Network in the original game.

Behind the scenes
The Pneumatic Diversity Vent was first introduced during the Portal ARG, in one of the ASCII art images given by the BBS, that later appeared to be an informative poster depicting the Plate's operation.
