EC Forward and Backward Curved 170W

Our EC motorised impellers utilise the latest three-core technology, ensuring best in class efficiency levels as well as whisper quiet operation. This range of EC centrifugal motorised impellers and fans is optimised to provide aerodynamic efficiency and low acoustic noise at the higher static pressures encountered in today’s ventilation applications.

 

 

  • Lower speed of operation than backward curved fans
  • Compact impeller design
  • Cost-effective pressed steel or aluminium construction
  • Can be used for high temperature applications
