EC stands for Electronically Commutated and refers to the type of technology used in the design of these high-efficiency fans. They are more efficient than traditional centrifugal fans, the cost of maintenance is reduced as there is no fan belt to maintain. Adjusting speed based on changing needs, the reduction in speed can provide 50% savings in fan power consumption. Contact Dalroad for further information on the LS EC fan range on 01582 505 252 or email firstname.lastname@example.org.
The motor used is a permanent magnet brushless DC type and the on-board PWM controller uses high speed switching instead of brushes to power the fan.
