Belimo's NFB Series Damper Actuators

Belimo, the industry leader in Air Flow Controls, sets the standard for damper actuators in the HVAC market.  Their NFB Series is a type of “Mechanical Fail-Safe” which means these include an internal mechanism that stores energy to drive an actuator motor to it’s predetermined ‘safe’ position in the event of power loss.

The New Generation NFB/NFX series of spring return actuators was designed for several applications including control valves, make-up air units, retrofit, replacement and control dampers designed up to 22 square feet. 

The NFB24 Damper Actuator

Here are some of the benefits and features of the series:

• Torque: With 50% more than previously offered, the NFB series now boasts 90 in-lbs of torque.
• Smaller Housing:  The re-design of the body features a reduced footprint with the edge to shaft-center distance shortened by .75” which makes the device easier to install in tighter spaces.  
• Manual Override:  Now standard on all NF Series configurations.
• Power: UPS can accept 24 VAC (up to 24) VAC.  The actuator is ideal for all power supply voltages.
• Cable length options: Now offered are 3’, 10’ and 16’; same as the non-spring return models.
• Mechanical limit stop:  This is now built-in, and no longer a separate accessory.

Belimo Damper Actuators provide versatile operation and yield energy savings with their low power usage.  They perform reliably and safely, by utilizing rugged components.  They communicate directly with BAS (Building Automation Systems) via BACnet, Modbus or MP-Bus.  Finally, they offer unsurpassed accuracy and control without loss in their performance due to supply voltage, temperature, or speed.

Since 1975, Belimo Air Controls has been the leader in field devices for the HVAC industry.  Find the Belimo NFB Series or any other damper actuator the produce at E-Controls.net
