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. + Choice of two operators:
- Standard: features a slotted lever for adjustment with a standard flat screwdriver.
- Lever: features a face accessible lever and is ideal for products with restricted access at the diffuser face such as linear bar grilles.
+ Optional duct mounting allows the damper to be installed further upstream in the ductwork to minimize generated noise in the occupied space.
+ For optimum flexibility the VCS3 can be mounted directly on a diffuser or grille, or shipped as a standalone product for
field installation.
