The EC axial-flow cooling fan is electronically commutated fan, represents a blend of the advantages of AC and DC cooling fans. They harness the power of AC power while harnessing the precision of DC motor technology through an integrated variable speed control system. This innovative combination can lead to significant efficiency gains, often up to 90%. While EC fans may have a high upfront cost initially, their long-term reliability and potential cost savings make them a worthwhile investment. EC axial fans are widely used in HVAC systems, and commercial and residential air handling units. In addition, in recent years, strict environmental regulations have driven the adoption of compact EC axialcooling fans in various industries.
