EC axial fans have been designed as drop-in replacements to existing AC axial fans. The motor is a brushless DC construction, which results in a range of higher airflow versions available. These fans can produce up to 40% more air flow compared to existing AC axial fans. This is significant for end users in the HVAC, data center equipment, avionics, railway and medical industries who are struggling with increased operating costs. EC axial fans offer a big part of the solution by reducing the energy consumption of devices.
