Osborne Smooth Radius Duct Elbow
The Osborne Smooth Radius Duct Elbow prioritizes airflow efficiency by using a long-radius internal profile that reduces turbulence and pressure drop, making it a technically superior choice where fan energy and uniform ventilation are important. Compared with the sharper Canarm 90° model it offers measurable energy savings over time, and it is typically less expensive than fully insulated or adjustable systems while delivering better airflow performance in mid- to large-scale barns.
