Available in clockwise and counter clockwise rotation
  • A perfect match of fan and motor design
  • Brand new motor design meets the high torque requirements of the 12 bladed rotor
  • Highest efficiency of 70-71% (fan-motor-controller) notwithstanding the high torque concept long flying times plus high power input without damages or overheating
  • 12-bladed rotor for lower rpm and high flow deflection CFRP-Aluminum design with ultra-thin rotor blades and high modulus carbon fiber shroud
  • Perfect true running because of collet rotor mount
  • 3-phase wiring perfectly integrated at the fan shroud
