Electronically commutated (EC) motors combine the efficiency of brushless DC technology with integrated electronics that match speed precisely to demand. In typical ventilation duty, this delivers energy savings of up to 50% over conventional AC fans with throttling or damper control.
GTM EC fans reach IE5 efficiency levels and comply comfortably with the EU ErP 2015 thresholds. With soft-start, full speed control and condition monitoring built in, they also reduce mechanical stress and extend service life.
