Axair Fans has established long term partnerships with manufacturers s.a. (France) and Gmbh (Germany), and are now able to offer Energy Efficient EC fans and air movement products. Both Ecofit & Rosenberg develop and manufacture their own motors and fans. The Ecofit EC range use motors from 65 up to 113Wa, the Rosenberg range use motors from 1.1 up to 3.4Kwa motors.EC stands for Electronically Commutated and it combines AC and DC voltages, bringing the best of both technologies : the motor runs on a DC voltage, but with a normal AC supply. DC motors already have low power consumption but if used in an AC application, the power needed converting AC to DC, using a bulky, inefficient transformer. The EC motor incorporates voltage transformation within the motor. The non-rotating part of the motor (stator) is extended to make room for an electronic PCB board which includes power transformation AC to DC, as well as the controls.
All the features of the are kept, including compact assembly, easy speed controllability, efficiency and characteristics.
