The RL regulation louvre is a compact and robust damper for controlling airflow in ventilation systems. Manufactured from galvanized steel with ABS bearings and gears, it ensures long-term durability. The damper uses opposed blade operation and supports both manual and motorized control, including ATEX-rated actuators (24V or 230V). With a maximum pressure differential of 1000 Pa and operating temperatures up to 70°C, RL is suitable for various industrial and commercial HVAC systems. The unit also provides airtight operation with Class C casing and Class 3 blade sealing, ideal for precise airflow regulation.
