New Generation AF and NF spring return actuators
raises the bar for actuator quality, reliability and technical superiority.
periority.
• Increased torque for more demanding
applications: 180 in-lb (AF) and 90 in-lb
(NF).
A lot more in much less.
• Smaller housing for tight spaces and
easier handling.
creased torque to 90 in-lb (50% more compared to original NF series)
• Faster motor run times with MFT
technology: 70 seconds with new AF
and 40 seconds with new NF.
running times (with MFT technology) offer new solutions for control
• Universal power supply (for On/Off
models) can accept 24 to 240 VAC
offering you one actuator for all voltages.
The New Generation can be integrated with new and some existing
• Manual override is now standard on all
models for faster installation and easier
servicing.
New AF and NF spring return actuators provide more features in a
smaller housing, about 25% smaller! Low power consumption, inand 180 in-lb (35% more compared to the original AF series), and faster
dampers, control valves and retrofit applications.
Belimo accessories allowing for more options in both mounting and
commissioning. A wide selection of clamping options, electrical
connections and running times are now available providing you a cost
effective solution with the same reliability you have come to experience
with Belimo. The New Generation spring return actuators are suitable
for use in control dampers up to 45 square feet* (with new AF) and up to
22 square feet* (with the new NF), air handling units, control valve,
retrofit and replacement solutions and tandem mounted applications
where higher torque is required.
*Parallel blade without edge seals and 1000 FPM face velocity.
New Generation – more features
and benefits in a smaller size.
