The rotors of these fans are equipped with straight backward-leaned blades. A CFDaided iterative design process has served for ensuring fan efficiency meeting the legislative requirements. Measurement-based loading, efficiency and power curves are presented on surveying how rotor widening can further increase the flow delivering capability of the fans. Industrial on-site Phased Array Microphone experiments are reported on the acoustic features of the new fans, as contribution to product development. Based on these tests, preliminary studies on the potential of acoustics-based fan condition monitoring are discussed.
