Louver Damper Valve for Industrial Ventilation & Dust Control
（Katup Damper Louver untuk Ventilasi Industri & Pengendalian Debu）
High-efficiency multi-blade louver damper for precise airflow control, dust extraction, and industrial ducting systems
Overview
The Louver Damper Valve is a multi-blade industrial damper designed for precise airflow regulation, dust control, and pressure balancing in large ventilation ducts and material handling systems.
Compared with butterfly dampers, louver dampers provide larger flow area, smoother modulation, and better volume control, making them ideal for baghouse filtration systems, cyclone separators, pneumatic conveying networks, furnaces, boilers, silos, and industrial exhaust lines.
Its robust construction allows reliable operation under high dust load, high temperature, and continuous-duty industrial environments.
