Product Details
- Voltage240 VAC
Description
The NFB and NFX series actuators provide true spring return operation for reliable failsafe application and positive close off on air tight dampers. The spring return system provides constant torque to the damper with, and without, power applied to the actuator.
- Cut labor costs with simple direct coupling.
- True mechanical spring return - the most reliable fail-safe.
- Mount for clockwise or counterclockwise fail-safe.
- Check damper position easily with clear position indicator.
- Don't worry about actuator burn-out. Belimo is overload-proof throughout rotation.
- Easy mechanical stop to adjust angle of rotation (add ZDB-AF2 US accessory).
- Need to change control direction? Do it easily with a simple switch (modulating actuators).
- Golden Point breather membrane optimizes performance in harsh airstream environments.
- Microprocessor-controlled brushless DC motor increases actuator life span and reliability, provides constant running time (modulating actuators).
- Rugged metal housing withstands rough handling in the mechanical room.
- 3 ft. appliance rated cable and conduit connector eases installation.
