HyBlade ebm-papst: hybrid fan blades

HyBlade is an axial fan blade technology developed by ebm-papst. A good place to start is its construction: an inner aluminium element works with an outer section made of glass-fibre-reinforced plastic.

What does the hybrid construction offer?

Combining the materials makes it possible to bring together the rigidity of the supporting structure and the ability to shape the blade’s aerodynamic profile. The manufacturer’s materials associate the development of HyBlade with reduced weight and noise, as well as improved airflow performance compared with earlier solutions.

Blade shape and noise

An important feature is the blade tips, known as winglets. We cover the research and causes of sound generation separately in our post on reducing noise from HyBlade fans.

AC and EC are separate design characteristics

HyBlade blade technology is featured in materials relating to fans with AC and EC drives. The blade designation alone does not indicate energy consumption or the device’s overall characteristics. Comparing models requires data for the relevant operating point and the specific fan design.
