Z-shaped Round Aspiration Duct Adapter

The AD-OK-A Z-shaped round aspiration adapter (commonly known as a “duck”) is a special ventilation fitting designed to connect round aspiration ducts positioned at different vertical levels or horizontally offset from each other. It is used when ducts are located above or below one another or shifted to the left or right.
The Z-shaped configuration allows reliable integration of ducts in confined or complex installation conditions while maintaining airtightness of the aspiration system. Such adapters are widely used in aspiration, dust extraction, and industrial ventilation systems to ensure proper airflow distribution.
In addition to connection functionality, the adapter helps reduce excessive air velocity in critical sections, decreasing vibration loads and mechanical stress on ductwork, thus improving overall system durability.
The adapter is made of galvanized steel. Flange height — 6 mm.
