How the profiles compare
Air velocity through each Ductlab profile at the same airflow — the flatter the duct, the faster the air has to move.
Velocity is calculated from each profile's nominal free area (v = airflow ÷ area). Use it to compare profiles; refer to the installation guide for recommended limits.
