NEW! The Airvector® ADLD Series is a high-performance line of drum louvers specifically designed for mounting on round or spiral ducts. Engineered for large open spaces requiring long throws and precise airflow control, the ADLD combines aerodynamic performance with robust construction and architectural integration.
Each unit features a rotatable cylindrical drum with individually adjustable internal vanes, allowing for full control of both vertical trajectory and horizontal air spread. The curved frame ensures direct mounting on round ducts without the need for duct taps, reducing installation time and maintaining a clean, professional finish.
