For Permanent Storage of Ghosts
Ghostbusters: The Video Game
The Containment Unit (known as the Storage Facility or Protection Grid in the first film) is a large machine in the basement. It is a large laser confinement grid that holds and restrains all the vapors and entities that the Ghostbusters trap.
Created in: 1984
Walter Peck visited the Firehouse because he was concerned about dangerous and potentially harmful waste that the storage facility might be producing. When he failed to convince Dr. Venkman to show him the storage facility, he came back with a search warrant. After instructing a city worker to turn off the containment grid, the system blew up, releasing all of the captured ghosts back into the city.
Ghostbusters: The Video GameEdit
In the Realistic Version of the 2009 video game, the Containment Unit is shown to have incorporated some visual elements from the cartoon version. Egon recently added a viewer to the unit, something that fascinates Slimer. At the beginning of the Thanksgiving holiday, the Rookie accidentally shot it and released the Sloth Ghost. Egon adds he was fine-tuning the interspatial gasket in the afternoon and gets to work on fixing the unit.
The unit is unchanged from its film appearance in the Stylized Version. The Player can dump a fresh trap into the Containment Unit after each level by interacting with the lever on the right side of the screen.
Secondary Canon HistoryEdit
The animated series shows that the machine transports the ghost to a strange dimension where they are free to roam around. The dimension seems to vary at times from a brightly colored realm with card tables to a dark realm of destruction. The animated version was also notably larger than the movie version, due to Egon's decision right after the Gozer encounter to build a much bigger one. Though improved from the film version, the animated version still has its faults.
- In the earlier Activision Ghostbuster video games for many platforms, a portable containment grid could be purchased for use on the Ecto-1 vehicle, eliminating the need to return to HQ to empty traps.
- The containment grid also appears in the arcade game and the ending cutscenes of the PlayStation game
Legion Mini SeriesEdit
The Containment Unit, six months after the Gozer incident, resembles the version seen in The Real Ghostbusters.
Stuck in the Old West era, Peter Venkman made his own Containment Unit, as close as he could jury rig, to hold the ghosts suddenly appearing. The last known entities deposited in it were The Rudely Mallard Gang.
A new group of Poltergeists possess a unique energy signature different from a standard entity. This development allows these entities to escape the Containment Unit. During the breach, the Stay Puft Marshmallow Man also escapes. After Egon jury-rigs a zombie radar to track the Zombies, he decides to move it downstairs into the basement and connect it to the grid's generator for more power.
There seems to be a limit to the amount of ghosts that can be contained in the Mark l containment version, as evidenced by Egon's statement that the facility was getting crowded. However the limit is unknown, since Peter was not at liberty to disclose the number. The storage facility works in much the same way as a ghost trap works, in that it is tuned to the same ionization rate of the ghosts.
The storage facility is a concept that Dr. Stantz and Dr. Spengler theorized when they gathered data during a close contact; under the provision that the ionization rate for all ghosts remained constant.

- In the October 7, 1983 (Also referred to as "Final Shooting Script") draft of the Ghostbusters script, there is a camera inside the Containment Unit which allowed the Ghostbusters to monitor incarcerated spirits via closed-circuit television. It was described as "a bleak repository for souls of many species. Strange lights, mists and spectral shapes waft about aimlessly. Human-like figures lean against the walls in despairing convict poses. Others flit and hand on the ceiling. It is a sad and frightening limbo and a most unholy makeshift asylum." Even Venkman declared that it was "too depressing" to watch the goings-on inside. 
- In Ghostbusters: The Supernatural Spectacular, when Winston is first introduced to the Containment Unit, he peers through the view slit. One ghost "drifts to the viewport and stares back, like a grouper in an aquarium." The Unit is also described to have three slots or airlocks of different sizes for each of the custom traps that Ray Stantz put together. It is noted the type of trap Stantz uses to demonstrate with to Winston is a Mark II.
