Focus on EC fan only
he centrifugal fan is a machine that relies on the input mechanical energy to increase the air pressure and discharge the air distribution.
If the vortex center is far away from the vortex tongue, the circulation flow area will increase, the fan efficiency will decrease, and the flow instability will increase.
EC stands for Electronically Commutated, and it combines AC and DC voltages bringing the best of both worlds. Today we will give you a brief introduction of EC fans.
