The RD regulation damper is a versatile solution for controlling airflow in circular ventilation ducts. Made from galvanized steel, it features both manual and motorized operation. For diameters ≤ 250 mm, a plastic self-locking mechanism is used, while larger sizes (D > 250 mm) come with a durable metal control system. The damper supports various actuator types (24V/230V, ATEX-rated), operating reliably in temperatures up to 70 °C. Ideal for commercial and industrial HVAC applications, the RD damper ensures precise air regulation with optional continuous or two-position control.
