About EC Axial Fan:

1: EC stands for Electronically Commutated, and it combines AC and DC voltages bringing the best of both worlds.

2: The motor runs on a DC voltage, but with a normal AC supply. The motor incorporates voltage transformation within the motor.

3: 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.

4: Brushless DC motor / fan driven by AC source input.

The EC fan is more windy than the AC fan, more energy efficient, and can work in the 70V - 270V voltage range, such as work under on 110V, 115,120V, 220V, 240V ,the fan speed are the same.

Material Flame Retardant:
Made from insulated material,
Which is flame-retardant,
Corrosion resistance,
Long service life. It can prevent electrical leakage.
