EC fans includes AC driven brushless DC fan with integrated design of AC-DC transformation circuit,the PFC circuit,the BLDC drive circuit,interface circuit.Due to the internal integration of the AC-DC converter circuit, the consumption of power will be reduced to facilitate the design and application of the overall power system in customer.

As the rotor is mounted to interior,the external rotor fan is more compact constructed,smaller and easy to abstract heat,thus ensure to maximum the  reliability of fan operation.

The EC axial fan has been widely used in various fields, especially ventilation,large air conditioning and refrigeration.  The compact structure and continuous controllability of EC centrifugal fan has been into full play to air handling units,computer modules,communication systems, clean room systems,roof fans,home machine,automotive and rail technology.
