fans are essentially fans with brushless Dc motor, combining theadvantages of Ac and Dc power.Air PurificationApart from smart control and energy-saving, the compact size is oneof the significant features of EC fans.RefrigerationEnergy-saving is the most important feature that will be taken intoconsideration because the evaporator fan motors run twenty fourhours a day.Automotive equipmentThe EC brushless motorized fans can be used both in combustionengine thermal circuits and in electric vehicles.Medical EquipmentEC fans, with high performance, efficient energy consumption, lownoise level,etc, are also favored in medical industry.Packaging & ShippingDomestic:7 days, Foreign: around 12 days old opening within 45 days of R&D.
