The best example: HyBlade®


An outstanding example of the continuous further development and improve- ment of our products is HyBlade®


developed specifically for large axial fans. HyBlade®


– a one-of-a-kind material composite brings the benefits


of two opposite materials to their lowest common denominator: maximum efficiency.


For one, a carrier made of aluminium provides high stability. For another, the attached sleeve made of fibreglass-reinforced plastic permits com- pletely free mouldability of the blades. Where metal can be machined only by bending, stamping and punching, fan blades with the HyBlade®


struc-


ture can be optimised down to the finest detail, for example using winglets on the wing tips, like those that provide greater lift for aeroplanes. For the HyBlade®


, they enable even higher aerodynamic efficiency – with minimum 7


weight and revolutionary noise reduction. In conjunction with our highly efficient, leading edge drives with GreenTech EC technology, HyBlade®


become real energy-saving wonders. No wonder, then, that HyBlade®


fans has also become an international sensation.


For example, in early 2008, our product innovation received the iF material award (iF International Forum Design GmbH), the renowned prize for out- standing material solutions.


HyBlade® fans are available in many familiar sizes and with standardised interfaces. This makes it particularly easy to switch to our lightweight fans.
