Low Price and Electric Damper Actuator

Ningbo Star Win Actuators Manufacture Co.,Ltd  has focused on top quality HVAC parts for over 30 years in China. We started as a transmission parts, stamping parts factory, but now have become one of the leading suppliers of the air damper actuators in the HVAC field in China. 

We now have the 5Nm spring return electric damper actuator(analogy BLF), the 15Nm reverse electric damper actuator( analogy BLE), the 6Nm, , 10Nm, 16Nm, 25Nm, 40NM on/off type electric damper actuator(analogy NM, LM, SM, GM), and 6Nm, 10Nm, 24V modulating electric damper actuator( analogy NM) and some other manual actuator. 

For we are born of machinery parts factory, all the damper actuators parts are made by our own, the quality and delivery time can be controlled well, and keep our cost lower, to help you source the reasonable price actuator to win the market well.


This air damper actuator is special designed for small and medium-sized air damper as well as for terminal control unit of air volume system. It is usually used in somewhere space limited because of its small size and flexible control.
Caution:

1. Operation must by professional personnel
2. Check the voltage and control method first to avoid the actuator damage for wrong connection, forbid power on making connection, Short circuit between line and line also will make actuator disintegration 
3. When many actuators work in parallel, the same color wire must connect in parallel on a same power wire, or actuators will burnout
4. When change any actuators rotate direction in parallel work actuators, should operate on the Profile reversing switch, forbid to realize it though the Switch opening and turning off the connection 
5. If have any doubt on the wire connection or installation forbid to trail run with power on, must be consultant with the manufacture to confirm all fine

Change the rotate direction
the switch on the side shell, pull it can change the rotate direction 
Change the control signal(for NM type) 
The actuators default control type is 0~10V, if want to change as following method:
A,2~10V control method: turn on the dip switch 2( default is off position);
B,0~20mA control method: turn on the dip switch 1(default is off position);
C,4~20mA control method: turn on the dip switch 1 and 2 both
