A 100mm pre-fabricated duct refers to a type of ductwork used in HVAC (Heating, Ventilation, and Air Conditioning) systems that comes pre-made or pre-constructed in standard sizes, in this case, 100mm in diameter. These ducts are commonly used for both residential and commercial applications to distribute heated, cooled, or ventilated air. The "pre-fabricated" term indicates that the duct is manufactured in advance in a factory, often ready to be installed directly into the system without requiring on-site fabrication.
