EC stands for Electronically Commutated. An EC fan is essentially a fan with a brushless DC motor which runs on a normal AC supply. EC fans are driven by energy-saving motors with an EC unit which means they operate at optimal efficiency. To put this into perspective, the efficiency of an EC fan is 80 - 90% where as an equivalent AC fan will only achieve between 60 - 75%. Using an EC fan means you will make big cost savings over the lifetime of the fan.
