The DUNLI EC Axial fan is the latest thing in energy efficient air movement technology. EC stands for Electronically Commutated, which in simple terms,means it is a fan with a brushless DC motor. These are easier to control, have a BIG speed range, low temperature rise, motor efficiency is high (>80%)and not effected by power frequency. Simply put these are energy saving and helps with emission reduction, which in some parts of the world is becoming an ecological requirement.
