Diversity Vents (Mechanic)

The Pneumatic Diversity Vent was a cut testing element during the E3 Era, it was cut due to not fitting with other Gameplay Mechanics and not being great for Portal 2 puzzles. It would have sucked up many objects such as Weighted Storage Cubes, Turrets and even wall panels. Their models were re-used as decoration after their eventual cut.

Even if the testing element was cut, the Pneumatic Diversity Vents were used in Chapter 5 of Portal 2, where Chell and Wheatly escape GLaDOS by using one. They also appear in the CO-OP Hub as an entrance and exit to the Art Therapy section of the game. There are also many times where GLaDOS uses these during scripted moments during the Campaign of Portal 2
