The landscape of fan design is rapidly evolving to meet the escalating demands for higher efficiency, reduced noise levels, and increased availability. Moreover, with many fans now serving safety-related applications, the need for innovation has never been more pressing. The advent of connectivity and digital services is catalyzing the emergence of novel business models, while the prevalence of variable speed introduces new design challenges for plant upgrades.
In this dynamic environment, numerical simulation techniques are becoming indispensable tools in aerodynamic design processes.

Fan 2025 offers a unique platform for fan and system designers, manufacturers, and operators to come together and advance our understanding of fans and their intricate system interactions.

This event will be a forum for fan and system designers, manufacturers and operators, with the aim of improving our understanding of fans and their system interaction. Fan 2025 will follow a three-track format. Each track is separate, but complimentary.

This three-day conference will include keynote lectures and technical presentations. The technical presentations will be organised as three technical tracks, focusing on fan noise, fan aerodynamics, fan applications and systems. All types of fans, such as those used in industrial process, HVAC, electronic equipment, household appliances, automotive and traction fall within the scope of the conference. Conversely, high speed fans in aeronautical propulsion applications will not be included.
