Fans combine DC performance with AC convenience

ES June13 Pg26 What's New AercoAerco has been appointed exclusive European distributor for American fan manufacturer, Sofasco. The line-up includes a new breed of frequency switching fans that have AC power input, but incorporate circuitry that delivers DC power to the fan motor.

The use of a frequency switching motor is said to bring many advantages over a conventional AC fan. It promises high temperature endurance, long life, high reliability, low power consumption, wide input voltage range and smart multi-function controls. Thanks to a patented Sofasco design that reduces the hub area and increases the size of the impeller, it also provides double the airflow of a conventional AC fan of the same size.

Although marginally more expensive than traditional AC fans, Aerco expects the technology to be attractive to the European market because of the energy efficiency it provides and the fact that it can easily be designed into intelligent thermal management systems, thanks to speed control.
