A Multi Louver Damper is a type of mechanical device used to regulate the flow of air, gases, or liquids in ventilation, HVAC, or industrial exhaust systems. It consists of multiple adjustable blades (louvers) that can open or close to control airflow. These dampers are commonly used in applications requiring fine control of air or gas flow, such as in air conditioning, heating, and exhaust systems, as well as industrial ventilation.

Key Features

• Multiple Blades (Louvers): Unlike a single flap damper, the multi-louver damper is made up of several parallel blades or louvers, which can be independently adjusted. This provides more precise control over airflow.
• Adjustable Control: The position of each louver can be controlled manually, pneumatically, or electrically, allowing the user to control the airflow to a much finer degree.
• Materials: Multi louver dampers are typically made from steel, stainless steel, aluminum, or galvanized steel, depending on the specific application, the type of airflow (air or gas), and the environment (corrosive or high-temperature conditions).
• Sealing: The blades are often equipped with seals to ensure minimal leakage when the damper is closed, preventing the unwanted passage of air or gas.
• Corrosion Resistance: Multi louver dampers used in corrosive or industrial environments may be coated with protective finishes to resist rust and degradation.
