Special features/product advantages
  • Efficient energy usage.
    The innovative blade geometry and energy-efficient IE3/IE4 motors ensure the best possible specific thrust coefficient. At the same time, this reduces your energy and operating costs.
  • Consistently reliable.
    The low-wearing GFK/PA6 propeller is durable and scores with its self-cleaning effect.
  • Smooth running thanks to the balanced propeller load, even in high thrust ranges and when incoming flow conditions are unfavourable.
