Opposed Blade Damper (Model VCS3)

The VCS3 opposed blade damper provides airflow adjustment at the grille. Volume control blades move simultaneously in opposite directions to provide superior metering and control with minimal disturbance of the air pattern. For optimized sound performance it is recommended to match an upstream duct branch damper for large volume control with a damper at the diffuser for fine tuning. Optional damper for Price Industries' Model 530 Louvered Return Air Grille and Model 80 Egg Crate Return Aire Grille.
