BELIMO NM24A

When managing airflow in HVAC systems—whether in VAV/CAV units, ducts or ventilation installations—having a reliable and precise damper actuator is vital. The BELIMO NM24A actuator is designed to meet that need. It provides a strong 10 Nm torque, allowing it to operate dampers of up to approximately 2 m² size. With a standard AC/DC 24 V supply, it can integrate easily into global installations and retrofit projects. The modulating control (open/close, or 3‑point) allows the actuator to deliver accurate positioning of dampers, enhancing air delivery and balancing comfort and energy efficiency. Installation is simplified thanks to the universal shaft clamp covering Ø8…26.7 mm, meaning fewer parts needed and compatibility with a wide variety of shafts. The manual override push‑button supports maintenance and commissioning tasks without full disassembly. The IP54 housing ensures the actuator withstands typical indoor HVAC environments—dust, light spray and general wear—offering durable performance. Compared to generic open/close actuators, the NM24A is superior in precision and flexibility of control, better suited for professional HVAC zones where balanced air‑flow and stable control matter. For building‑automation integrators and contractors, the NM24A offers a strong, cost‑effective solution with long service life and simpler installation.
