Description
The BELIMO NM230A‑S actuator provides a simple yet robust solution for controlling air dampers in HVAC, ventilation, or smoke‑control systems. It is designed to operate dampers up to approximately 2 m² — enough for most residential or commercial ventilation ducts and airflow control setups. With 10 Nm torque and universal AC 100–240 V supply, NM230A‑S works reliably across a broad range of power supplies, making it suitable for retrofits or new installations across diverse building infrastructures.
