Manika

Origin

The term is derived from the Italian word "manica," which means both "sleeve of clothing" and, in maritime terminology, "cargo hold vent." The historical origin of the term traces back to the Latin word "manica," which also denoted "sleeve." The technical meaning emerged from a formal resemblance between the physical structure of ventilation shafts on ships and the shape of a clothing sleeve.

Applications

• Maritime: Used to describe the processes and technical equipment employed for natural ventilation of enclosed spaces on ships such as cargo holds, engine rooms, and lower decks.
• Engineering: Preferred in technical descriptions concerning the placement and design of vertical air ducts in industrial structures or shipbuilding projects where control of airflow is required.
