An example air duct setup using all of the air duct parts.
Air Duct Parts are a selection of 6 parts all at a classification of light weight, with the title heading of "Duct". They can be used together to create long, bended and interconnected air duct systems. Air ducts don't have any function in the game, and this collection of parts only serves a decorational purpose.
None of these parts can be crafted using the Craftbot.
