Usage Note
conduit refers to a channel or pipe carrying air, liquid, or electrical cables — un conduit d'aération is an air duct. Note that this noun is also the third-person singular past participle of conduire ('he drove / he led'), so context is needed. The plural conduits is pronounced the same as the singular.
Examples
"Le conduit d'air est bouché."
Natural Translation
The air duct is blocked.
