Information About NF24 US
The NF24 US is part of Belimo’s spring return damper actuator series engineered for reliable airflow control and safety positioning. It incorporates a robust spring mechanism that automatically returns the damper to a defined position during power loss, supporting system protection requirements. The actuator includes an SPDT auxiliary switch for position indication or interlocking with control systems. Designed for commercial HVAC installations, it features durable construction and conduit-ready wiring for straightforward field installation.
Key Features
- 60 in-lb Torque Output: Provides sufficient mechanical force for accurate positioning of medium-sized HVAC dampers under normal operating conditions.
- Spring Return Fail-Safe Operation: Automatically drives the damper to a predetermined safety position when power is interrupted.
- 24 VAC Power Supply: Compatible with standard low-voltage HVAC control systems commonly used in commercial buildings.
- On/Off Control Function: Supports simple and reliable binary damper operation for ventilation and zoning applications.
- Integrated SPDT Auxiliary Switch: Enables precise position feedback, interlocking, or signaling to building automation systems.
- Conduit-Ready Electrical Connection: Equipped with a 1/2-inch conduit interface and prewired 3-foot cable for easy installation.
- Durable Mechanical Design: Built to withstand continuous operation in demanding HVAC environments with minimal maintenance.
The NF24 US delivers the reliability and precision required for safe, long-term spring return damper control in commercial HVAC airflow management applications.
