The Air Movement and Control Association (AMCA) International Inc. launched ANSI/AMCA Standard 207, Fan System Efficiency and Fan System Input Power Calculation. It was approved by AMCA membership April 12, 2017 and approved by the American National Standards Institute on April 17, 2017.
ANSI/AMCA Standard 207-17 provides a method to estimate the input power and overall efficiency of an extended fan system, which is composed of a fan and an electric motor but may also include a transmission and a motor controller. While direct measurement of fan system performance is preferred, the large number of fan system configurations often makes testing impractical.
This standard offers a standardized method to estimate fan system performance by modeling commonly used components. Calculations reported in accordance with this standard offers fan users a tool to compare alternative fan system configurations in a consistent and uniform manner. Users must ensure that selected components have sufficient capacity and are configured to produce the desired results.
