Do you ever wonder where fan manufacturers get their fan performance numbers? Typically, we buy products based on recommendations from our friends or by reading the product information posted by the manufacturer. But when the purchase is expensive or plays a crucial role in our day-to-day life, we like to seek out an unbiased review, such as Consumer Reports. Although Consumer Reports doesn’t test the fan performance of large diameter fans, an association called AMCA creates standards to teach us how to test fan performance.
As you can imagine, testing fans, particularly large diameter fans, requires a good technique. AMCA, the Air Movement and Control Association International, is a not-for-profit association created to support fan manufacturers through education, networking, performance standards, and testing methods. Recently it released a new standard: AMCA 230-15.
