VKG Rectangular Backdraft Damper is used in ventilation systems to maintain unidirectional airflow and prevent reverse flow. These dampers are designed to ensure that air passes in the desired direction only, enhancing system efficiency and preventing backflow.
Description
Material and Usage Features:
The casing is standardly made of aluminum, but galvanized options are available upon customer request.
