Belimo NFX24 Damper Actuator 90 in-lb Spg Rtn 24V On/Off

Product Description

The BELIMO NFX24 is a damper actuator with 90 in-lb torque, spring return, and operates on 24V with on/off control. It provides 95° of rotation and includes a graduated position indicator. A manual override allows position setting without power. The actuator uses a brushless DC motor controlled by an ASIC and microprocessor.

• Spring return actuator with 90 in-lb torque
• Operates on 24V AC/DC power
• Features on/off control type

Product Highlights

This damper actuator is designed for reliable performance with its spring return system and precise control capabilities.
