A lot has happened in the field of fans in recent years. Especially in the field of fluid mechanics. The use of computer-aided simulation tools in conjunction with new materials and manufacturing processes has made it possible to achieve massive improvements in efficiency. This applies to both centrifugal and axial fans.

In addition, the EC motor has become widely accepted as a drive concept. This motor technology not only offers advantages in terms of energy efficiency, but also demand-oriented operation thanks to stepless controllability saves money.

This development holds enormous potential for existing plants whose fans are getting on in years. The lecture deals with the current fan generations and shows which performance classes and fan designs are particularly suit ...
