BELIMO NM24A-S

The BELIMO NM24A‑S actuator is designed to deliver smooth, dependable control for air dampers in ventilation, air‑conditioning, or HVAC systems. Its 10 Nm motor torque makes it suitable for dampers up to approximately 2 m², covering typical residential, commercial or light industrial airflow applications. Belimo+1

Since it supports both AC and DC 24 V supply, NM24A‑S is flexible for installation in diverse electrical environments — whether new projects or retrofit jobs. Control can be via simple open/close or 3‑point control, enabling integration with basic HVAC control panels or building automation. The built-in SPDT auxiliary switch provides signalling or interlock functionality (e.g. damper open/closed feedback), useful for system interlocks or BMS connections. Belimo+1

Installation is straightforward thanks to a universal shaft clamp (fits 8–26.7 mm shafts) with anti‑rotation feature, reducing time and complexity. For maintenance or manual adjustment, a push‑button manual override (lockable) allows manual damper operation without removing the actuator. Belimo+1

The actuator’s IP54-rated housing makes it resistant to dust and water splashes — a must for indoor HVAC / ventilation environments. Its low power consumption and modest noise level (~35 dB) ensure energy‑efficient, quiet operation — a great advantage over noisy or power-hungry alternatives. HVAC Sanitary+1

For HVAC contractors, building owners, or facility managers in Bangladesh or elsewhere, NM24A‑S offers a dependable, maintenance‑free solution for damper control — delivering consistent performance, long service life, and easy installation.
