Technology:  The core technology of the product is the complete integration of the transformer and drive electronics into the motor hub. The aerodynamic blade shape with added winglets contributes to improving the overall efficiency and significantly reducing the acoustic noise by up to 8dB. The drive concept of these energy-saving compact fans is based on the very efficient and durable ebm-papst GreenTech® EC motor technology. The combination of energy savings and extended service life means these fans pay for themselves in the short term and continue to pay for themselves over the long haul with every operating hour. See the table below for a comparison to the ebm-papst 4600Z shaded-pole AC fan.
