OUTSTANDING efficiencies and impressive control of the fan performance are available from the use of EC (Electrically Commutated) motors in fans.

This is displayed in the Gamma and PowerLine fans, the first of several product ranges with EC Motors that were developed last year by Fantech. A new 560mm diameter impeller has been incorporated into the fans, which provides a lower maximum speed than the existing version and a significant advantage in price. The new unit has a smaller motor, which, with less power consumption, also adds to the EC fan range’s ability to provide outstanding efficiencies.

As EC motors incorporate integrated electronics to regulate the fan speed, on site speed and therefore capacity adjustments, are simple. These motors also carry their own electrical protection and offer data read-out functions.

The Fantech GL Gamma Series is designed for use in commercial kitchen exhaust systems and other applications requiring the combination of speed-controllable motors with allmetal, roof mounted construction, while the standard Gamma unit provides many solutions for roof unit ventilation applications.

The PowerLine In-Line fans are an excellent all-round product, suitable for supply or exhaust of air in a wide range of commercial and industrial applications. As EC motors can be connected directly to a conventional single or three-phase AC supply, the overall cost of the installation would be comparable with a conventionally powered fan with control by frequency inverter.
