Applications

HVAC
EC fans are widely applied in HVAc systems, especially where speedcontrol function is required and noise reduction matters.

Cooling
EC fans are essentially fans with brushless Dc motor, combining theadvantages of Ac and Dc power.

Air Purification
Apart from smart control and energy-saving, the compact size is oneof the significant features of EC fans.

Refrigeration
Energy-saving is the most important feature that will be taken into
consideration because the evaporator fan motors run twenty four
hours a day.

Automotive equipment
The EC brushless motorized fans can be used both in combustionengine thermal circuits and in electric vehicles.

Medical Equipment
EC fans, with high performance, efficient energy consumption, low
noise level,etc, are also favored in medical industry.
