An increasing number of Fantech fans now include integrated speed control, such as our EC ranges of products, which were recently updated to include a complete set of in-line and roof mounted fans. In Advanced mode of the Select Fan section, tick the “EC/Integrated Speed Control fans only" check box to display only those fans.

When an EC fan is selected with a duty, the program will automatically scale the speed of the EC fan to meet that duty, and will display the performance and sound data at that speed.
