VIC manufactures Back Draft Dampers / Non-Return Dampers, which are primarily operated with respect to the air pressure at the inlet and allows only unilateral flow across its face. These dampers can be used for intake, discharge or pressure relief applications.
As the air pressure is being applied to the face of these dampers across the dedicated airflow direction, the blades open automatically and closes due to gravity or counter-weights as the air pressure is negated.
