CVS Combination Louvers act as a Louver/Damper combination. They utilize fixed louver blades in the front and adjustable blades in the rear that can be opened or closed with manual quadrant or electric actuator. These louvers are popular for warehouse applications and other structures in which you want to close the airflow without the use of a damper. CVS Combination Louvers are available in Extruded Aluminum, and Galvanized Steel and in different RAL finishes as per the project requirements.
