NF Series Spring Return Direct Coupled Actuator
®
● Cut labor costs with simple direct coupling.
● True mechanical spring return - the most reliable failsafe.
● Mount for clockwise or counterclockwise fail-safe.
● Check damper position easily with clear position indicator.
● Don’t wory about actuator burn-out.
Belimo is overload-proof throughout rotation
● Easy mechanical stop to adjust angle of rotation.
(add ZDB-AF2 accessory).
● Need to change control direction?
Do it easily with a simple switch. (NF24-SR
US)
● Golden Point breather membrane optimizes
performance in harsh airstream environments.

Torque min. 60 in-lb, for control of air dampers
Application:
For on-off, fail-safe control of dampers in HVAC systems.
Actuator sizing should be done in accordance with the damper
manufacturer’s specifications. Control is on-off from an auxiliary contact, or a manual switch.
The actuator is mounted directly to a damper shaft up to 1.05”
in diameter by means of its universal clamp. A crank arm and
several mounting brackets are available for applications where
the actuator cannot be direct coupled to the damper shaft.
Operation
The NF series actuators provide true spring return operation
for reliable fail-safe 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.
The NF series provides 95° of rotation and is provided with a
graduated position indicator showing 0° to 95°.
The actuator may be stalled anywhere in its normal rotation
without the need of mechanical end switches.
The NF24-S US version is provided with 1 built in auxiliary
switch. This SPDT switch is provided for safety interfacing or
signaling, for example, for fan start-up. The switching function
is adjustable between 5° and 85°.
The NF24-S2 US version is provided with 2 built-in auxiliary
switches. These SPDT switches are provided for safety interfacing or signaling, for example, for fan start-up. The switching
function at the fail-safe position is fixed at +5°, the other
switch function is adjustable between +25° to +85°.
