EC fans merge the best elements of AC and DC fans by combining AC power with DC motor technology through the use of sophisticated, built-in variable speed control. In many cases, this increased level of control can improve efficiencies by as much as 90%. While the advanced technology offered by EC fans comes at a higher price, the reliability and cost savings over time can make them worth the investment in the long run. EC fans are widely used in HVAC systems and other commercial and residential air handling units. More recently, strict environmental standards have made smaller-sized EC fan units popular in a variety of industries.

By combining the advantages of both AC and DC power, EC fans are the ideal solution for cooling electronic devices, like computers, vehicles, HVAC systems, and more.

EC Fan Standard Features and Specifications

One popular type of EC fan is an AC axial fan, which is used for applications that require constant cooling. 

Standard industrial specifications include:

  • IP55 dust- and moisture-protection.
  • 115V and 230V power options
  • Dual ball bearings
  • Dust- and moisture-protection
  • Class B insulation with a standard temperature clearance of 130°C.
  • The ability to perform reliably at operational temperatures ranging from -10°C to 70°C.
  • A lifespan of at least 50,000 hours at a standard temperature of 40°C.
  • •Simple operation and maintenance requirements.


EC fans intended for industrial applications should also comply with UL and CE standards and be RoHS-compliant. 

EC Fans Selection Guide

At Pelonis Technologies, we offer two popular types of RJ Series EC axial fans: RJ8038 and RJ1238. Both fans operate quietly and efficiently with a low power demand, extended life span, and few maintenance and repair requirements compared to other fan models. The primary difference between the fans is their size—the RJ8038 is slightly more compact.


The specifications of each fan type are as follows.
