Types of Air Ducts: Which One Should You Use for Your Project?

Choosing the right duct type in ventilation projects depends on many factors — available installation space, target airflow, acoustic requirements, and budget. The wrong choice can increase operating costs and lead to unwanted noise and inefficient air distribution.

The most common choice in height-restricted spaces such as suspended ceilings; it takes up less space than circular duct at the same cross-sectional area. It's the standard solution in office buildings, hospitals, and shopping malls.

Its circular cross-section provides lower friction loss and quieter airflow at the same flow rate. Preferred in warehouses and production facilities where exposed installation is not an aesthetic concern.

Combines the aerodynamic advantage of circular duct with the space-saving profile of prismatic duct; used in projects where duct height must be architecturally limited.

A flexible duct made from air-permeable fabric that provides homogeneous, low-velocity air diffusion across the entire space. Offers a low-noise advantage in sports halls and high-ceiling industrial buildings.
