The Air Ducts here at TG-88.3Ω are more or less functional. They are manufactured in sections and then fitted together to create a network.
Every duct system has an intake flow (marked ‘IN’) and an outflow (marked ‘OUT’). These mark the beginning and end of a duct network.
Why Ducts are Important
Ducts by definition allow the flow of a particular substance. In this case that subject is air. Without air ducts moving air around the facility, there would rapidly be no air.
Occasionally air ducts may show signs of manufacturing errors or other superficial damage. This does not affect air duct functionality, but care should be taken to ensure that damaged sections of duct are fitted together carefully to ensure a tight seal.
