When Fans Don’t Perform – Fan System Effects

Hello everyone and Happy Holidays! To kick the new year off we are having Mark W. Fly presenting on "When Fans Don't Perform - Fan System Effects". In general fans are thoroughly tested and perform to the published data if applied when applied similar to the tested configuration.  However, in application, this is not always the case if applied in a different configuration. This presentation will cover:

• How fans are tested and what configurations are used
• What are system effects and how do they effect fan performance
•  What configurations are likely to cause significant system effects
• What can be done to mitigate these system effects
