Fans sometimes get blamed for the underperformance of a system, but what if it is actually the other way around? This session discusses how fans and fan systems interact and impact the performance of one another. System effect is defined and discussed with real world examples. Recommendations for how to minimize or account for system effect are provided. The impact of changes in system resistance is discussed. The concepts of stability, stall and surge are reviewed, along with selection guidelines to help minimize risk.
