With the "Fan Technology Guide" written by our development engineers, punker offers a digital reference work to assist in the aerodynamic and aeroacoustic selection and optimization of ventilation systems and plants. In addition to the basics of aerodynamics and aeroacoustics, the various types of radial fan wheels and their aerodynamic properties are presented and criteria for fan wheel selection are explained. The topic of energy efficiency in the context of the EU's Ecodesign Directive (ErP) and the Fan Energy Index (FEI) for energy regulations and standards in the USA are addressed in detail.
The contents of the english language Fan Technology Guide are translated from the German language "Ratgeber Ventilatortechnik". Additional chapters and content will be added on a regular basis.
