90 in-lbs (NF Series)

The NF spring return actuators provide more features in a smaller housing, about 25% smaller! Low power consumption, increased torque to 90 in-lbs (50% more compared to original NF series) and faster running times (with MFT technology) offer new solutions for control dampers, control valves and retrofit applications.

  • 90 in-lbs [10 Nm]
  • Approximately 22 square feet
  • Run time 75…2200 seconds
  • Spring Return <20 seconds
