|Giant Spinning Duct Fan|
In every air duct, there will be one.Better Name Better Name Motion To Discard
- Brandon: You're deep in the underbelly of the Omega 13! Oh, it must be spectacular.Gwen: It doesn't look like much to me. There's just these few walls and this dumb spinning fan that's in every single...- Galaxy Quest
- The page quote comes from Galaxy Quest. At the bottom of the Omega 13 shaft is the ubiquitous dumb spinning fan - which is lampshaded.
- At the top of the fizzy lifting drink shaft in Willy Wonka and the Chocolate Factory.
- There's one in the air duct in The Fifth Element.
- In the air shaft in Alien3.
- Blade Runner arguably made the "big fan+steam+light shining through" a staple of Cyberpunk-Noirish media.
- Total Recall (1990). These can be found in the Martian colony's walls, where they pull in fresh air from other areas. At one point the Big Bad Cohaagen turns them off in one area in an attempt to suffocate the mutants who support Kuato.
- Seen in Iron Sky.
- The hitwoman of Columbiana is not only small enough fit in an air duct but through the blades of the fans in them.(Which may or may not break one's suspension of disbelief that one so tiny can last in fights with those who...are not)
- In the Doctor Who episode "The End of The World", the Doctor having to get to a switch blocked by gigantic spinning fans in a giant air conditioner area.
- Alias: One episode ended on a Cliffhanger with Sydney struggling not to get pulled upwards through an air vent into a huge fan.
- They're in almost every air duct in Half-Life.
- And in an air duct of Nova Prospekt in Half-Life 2.
- All over in the Underworld regions of Silent Hill. You're given the idea there must be huge air shafts behind them, but they're behind grates and inaccessible.
- There's one in the air vent of Gehn's study in Riven. Weirdly, the protagonist is able to squeeze into the tube once it's been turned off, even though the gap between the blades is a few inches at most.
- Some tunnels in the Metroid Prime series contain these. A few can be destroyed.
- Completely averted in Metal Gear Solid. Crawling around air ducts is a necessity, and there's not a single fan to be found in any of them.
- Deus Ex and Deus Ex: Human Revolution have duct fans as dead ends.
- A common element in the sewers levels of Crash Bandicoot 2. A few would even be so fast that one has to destroy it by ricocheting a nearby enemy (said enemy respawns after a few seconds for more ammo).
- In The Secret Of NIMH, as the mice and rats are escaping NIMH through an air vent a fan blows most of the mice to their deaths because they were lighter.
- In the third Futurama movie the crew sneaked into Mom's Alaskan base through the vents, the outer intakes had giant, red-hot spinning fans... one of which grazed Fry's butt.
- Obviously, air ducts do need to have a fan in them somewhere, but nearly all modern HVAC systems use centrifugal fans instead of the "axial" fans that appear in fiction. Centrifugal fans have lots of real-world engineering advantages (cheaper, quieter, more reliable, easier to scale up) but wouldn't look nearly as interesting from inside the duct, which is what matters in fiction.
- And that "somewhere" is usually special rooms that also contain air filters, AC, heat exchangers, dampers etc. These things is usually fitted into units that make it impossible to see a fan at all if one crawls around in the ducts. (Filters on the sucking side, dampers on the blowing and the other stuff somewhere in the middle.)
