Translation guide
A passage or conduit used to convey air for ventilation purposes. In Japanese, the term depends on context—whether it's part of a building's HVAC system, industrial ductwork, or a simple air pipe.
A duct that is part of a building's heating, ventilation, and air conditioning system, typically made of sheet metal or flexible material.
The most common and general term for a ventilation duct in buildings. '換気' means ventilation, and 'ダクト' is a loanword from English 'duct'.
換気ダクトの掃除を業者に頼んだ。
I hired a professional to clean the ventilation ducts.
Literally 'air passage duct'. Used similarly to 換気ダクト but slightly less common. Emphasizes the flow of air.
この建物の通風ダクトは老朽化している。

Specifically refers to air conditioning ducts. '空調' is short for 空気調和 (air conditioning). Use when the duct is part of an AC system.
空調ダクトから冷たい風が出てくる。
Cold air comes out of the air conditioning duct.
A duct used in factories, plants, or large facilities for ventilation, exhaust, or air supply, often made of metal and of significant size.
Explicitly 'duct for ventilation'. Used in technical or industrial contexts to distinguish from other types of ducts.
工場の換気用ダクトを点検する。
Inspect the factory's ventilation ducts.
Similar to 換気ダクト but '通気' emphasizes the passage of air. Often used in engineering contexts.
通気ダクトの設計図を確認する。
Check the ventilation duct blueprints.
A flexible hose or small pipe used for ventilation, such as in bathrooms, kitchens, or portable air conditioners.
Used for flexible ventilation hoses, like those connected to portable AC units or bathroom fans.
換気ホースを窓に取り付ける。
Attach the ventilation hose to the window.
Literally 'ventilation pipe'. Can refer to smaller rigid pipes used for air passage.
浴室の通風管が詰まっている。
The bathroom ventilation pipe is clogged.
A duct specifically designed to exhaust unwanted air, fumes, or smoke from a space.
Exhaust duct. '排気' means exhaust or emission. Used for ducts that remove air, smoke, or fumes.
排気ダクトから煙が出ている。
Smoke is coming out of the exhaust duct.
ダクト (duct) typically refers to larger, often rectangular or round sheet metal conduits for air in buildings. 管 (かん) is a general term for pipe/tube, often smaller and rigid. ホース (hose) is flexible. Choose based on the physical characteristics.
換気ダクトは金属製だ。
The ventilation duct is made of metal.
換気管を壁の中に通す。
Run the ventilation pipe through the wall.
換気ホースを伸ばす。
