A “trip wire” on the rear side of the blades near the leading edge.Strategically placed notches near the fan hub on the trailing edge of the blades further reducing the humming noise produced when the blades pass the stator struts.Stator struts sit on a wide angle to the trailing edge of the blades which result in a lower noise level and smoother noise profile.Helps reduce noise and unwanted turbulence Aerodynamically shaped stator struts including the wire strut.Fan geometry optimized for a good balance between static pressure and maximum airflow, resulting in good performance in all usage scenarios. ![]()
