Plain round duct

Plain round ducts are cylindrical conduits commonly used in heating, ventilation, and air conditioning (HVAC) systems to distribute air throughout buildings. The circular shape minimizes resistance to airflow, reducing pressure drop and energy consumption compared to rectangular ducts.

These ducts come in various diameters to accommodate different airflow requirements and space constraints. They are often installed in ceilings, walls, or floors, concealed from view to maintain aesthetic appeal. However, they can also be exposed in industrial or commercial settings where aesthetics are less of a concern.

Plain round ducts are assembled using joints and fittings such as Coupling, flanges, and connectors. Sealing these joints properly is crucial to prevent air leakage, which can reduce system efficiency and compromise indoor air quality.
