Profile

Damper is commonly used devices in air supply system,electric damper is composed of  electric actuators and damper.

Modulating electric damper could adjust damper opening degree,Control size of the wind.

Two type electric damper may play a role in closing and opening the duct.

If the requirement to open and close very quickly can choose quickly cut off damper, the full travel time can becontrolled in 6 seconds or 3 seconds.

DZF type electric damper is composed of DKJ series electric actuators and DF-type damper

BELLZF type electric damper is composed of BELL series electric actuators and DF-type damper.

SKJZF type electric damper is composed of SKJ series fast actuator and DF-type damper

　Features

DZF-F electric square damper with DKJ series electric actuators, easy installation and maintenance, economic and applicable. Modulating electric damper could adjust damper opening degree,Control size of the wind..

The main parameters of the actuator
