What is a tube or conduit utilized for conveying air called?

A tube or conduit utilized for conveying air is called a duct. Ducts are designed specifically to transport air from one location to another within a building or facility, serving various purposes such as heating, ventilation, and air conditioning (HVAC) systems. They can be made from various materials, including metal, fiberglass, and flexible plastic, depending on the application requirements.

Ducts play a critical role in maintaining indoor air quality and thermal comfort by distributing conditioned air and removing stale air from the environment. In contrast, a hood typically refers to a structure that covers or encloses a specific area, often used in kitchens or laboratories to contain and exhaust fumes or heat. A chamber generally refers to a closed space or room that may contain air but does not function as a conduit for air movement. A vent is often an opening that allows air to enter or exit a space but does not serve the same broad purpose of conveying air throughout a system as a duct does.
