Automatic Balancing Dampers (ABD) are popular in commercial buildings, as the provide precise and automatic airflow regulation in supply or exhaust ventilation systems. Designed for use in both supply and exhaust applications, the ABD's damper blade automatically adjusts position to account for changing pressures in the duct work. This is valuable as it minimizes energy consumption while also ensuring proper ventilation throughout your building. Watch the video below to learn why ABDs are a unique option in commercial HVAC systems.
