The design of fans has evolved to meet the ever-increasing demands for higher efficiency machines, combined with the requirements for lower noise and high availability. In addition, many fans are now being used in safety related applications plus connectivity and its associated digital services are driving the emergence of new business models. Variable speed is now more common, leading to some additional design problems and many existing users are revisiting their plant looking at ways to upgrade the fans. The use of numerical simulation techniques is also becoming an established part of aerodynamic design processes.

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 2022 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 applications and systems, fan noise and fan aerodynamics. 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.
