Description
The Belimo AFX24-SR-N4 is a heavy-duty, direct-coupled damper actuator engineered for demanding commercial and industrial HVAC applications. Powered by 24V AC/DC and featuring a spring return (S/R) fail-safe mechanism, this actuator automatically returns the damper to its safe position upon loss of power — a critical safety feature for smoke control, ventilation, and building automation systems.
Key Features
- 24V AC/DC power supply for broad system compatibility
- Spring return (fail-safe) operation for reliable damper positioning on power loss
- 180 in-lb torque output — suitable for large or high-resistance damper assemblies
- 2–10 VDC proportional control signal for precise modulating control
- NEMA 4 enclosure rating — protected against splashing water, windblown dust, and hose-directed water for indoor and outdoor installations
- Direct-coupled design eliminates the need for additional linkage hardware
- Manual override for commissioning and maintenance convenience
Application Highlights
- Ideal for variable air volume (VAV) systems, economizers, and outdoor air dampers
- Suited for wet or wash-down environments where NEMA 4 protection is required
- Compatible with building automation systems (BAS) using 2–10 VDC analog outputs
- Designed for commercial HVAC, industrial ventilation, and process control applications
