Product Description

7025 A Low Noise Axial Flow Fans EC Brushless Fan 70x70x25mm Brushless EC Cooling Fan

What is an EC axial fan?

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

The motor runs on a DC voltage but with a single-phase 230VAC or three-phase 400VAC supply.

The motor incorporates voltage transformation within the motor.

 

What is the difference between AC and EC fans?

An AC fan has an alternating current and is very expensive to control without making it hum or buzz.

An EC fan is basically a digital fan. It's a lot easier to control. Running an EC fan at half speed uses half the electricity.
