The Air Movement and Control Association (AMCA) launched the new ANSI/AMCA Standard 207, Fan System Efficiency and Fan System Input Power Calculation.

The designation for 207 is ANSI/AMCA Standard 207-17. It was approved by AMCA membership April 12, 2017, and was 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. An extended fan system 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.

AMCA says 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. This document does not provide selection guidance. Users must assure that selected components have sufficient capacity and are configured to produce the desired results.

“AMCA 207 offers a standardized method to estimate fan system power consumption and efficiency," said Michael Brendel, AMCA 207 committee chair. "It provides the fan industry and the engineering community with a consistent means to compare multiple fan system configurations when test data are not available."
