What Is The Difference Between EC Fan And Centrifugal Fan?


XieHengDa, a leading manufacturer of 60-170mm EC fans, DC axial flow fans, and EC centrifugal fans, is committed to providing high-quality, energy-efficient cooling solutions. The company’s product range includes EC blowers, electronically commutated fans, axial EC, EC centrifugal blowers, EC cooling fans, and EC axial fans. This article aims to highlight the differences between EC fans and centrifugal fans, two of the company’s flagship products.

EC Fans

EC fans, or Electronically Commutated fans, are direct drive fans that are integrated into the cooling unit by replacing the centrifugal fans and motor assemblies. They are inherently more efficient than traditional centrifugal fans because of their unique design, which uses a brushless EC motor in a backward curved motorized impeller. This design allows for a significant reduction in energy consumption, making EC fans a more sustainable and cost-effective cooling solution.

Centrifugal Fans

Centrifugal fans, on the other hand, operate differently. They use the kinetic energy of the rotating impellers to increase the volume of the air stream, which in turn moves against the resistance caused by ducts, dampers, and other components. While centrifugal fans are effective in high-pressure and high-flow rate applications, they are generally less energy-efficient than EC fans.


As a leading DC axial fan manufacturer, XieHengDa emphasizes the importance of energy efficiency in cooling solutions. EC fans, with their brushless motors, are up to 30% more efficient than traditional centrifugal fans. This efficiency not only reduces energy costs but also contributes to a more sustainable environment.

Noise Level

EC fans are also known for their quiet operation. The brushless motor technology reduces noise levels, making EC fans an ideal choice for environments where noise is a concern.

Speed Control

EC fans offer variable speed control, allowing for precise control over airflow and temperature. This feature is particularly useful in applications where varying airflow rates are required.


EC fans require less maintenance compared to centrifugal fans. The brushless motor design eliminates the need for regular replacement of brushes, reducing maintenance costs and downtime.


While EC fans are ideal for a wide range of applications, including HVAC systems, data centers, and refrigeration, centrifugal fans are typically used in applications that require high pressure, such as in industrial processes and air conditioning systems.


XieHengDa understands that every business has unique cooling needs. Therefore, we offer customized solutions to our clients. Whether you need an EC cooling fan with specific dimensions or a centrifugal fan with a particular airflow rate, our team of experts can design and manufacture a product that meets your exact requirements.
