ARLINGTON HEIGHTS, Ill., Aug. 2, 2023—Air Movement and Control Association (AMCA) International Inc. announces the publication of a new standard, ANSI/AMCA Standard 270-23, Laboratory Methods of Aerodynamic Testing Fan Arrays for Rating.

An adjunct to ANSI/AMCA Standard 210/ASHRAE Standard 51, Laboratory Methods of Testing Fans for Certified Aerodynamic Performance Rating, ANSI/AMCA Standard 270-23 clarifies and makes consistent and complete industry methods of testing and reporting the aerodynamic performance and fan electrical power (FEP) of fan arrays. It is limited to fans with direct-drive transmissions, including:

  • Optional calculation of fan shaft power based on motor calibration and measurement of the electrical input power of individual fans or an overall fan array.
  • Optional partitions between fans.
  • Optional appurtenances or design features affecting aerodynamic performance.
  • Optional speed controllers serving individual fans, groups of fans, or all fans of an array.

Informative annexes provide guidance on the use of ANSI/AMCA Standard 270-23 and the calculation of fan-array performance from tests.

The cost of ANSI/AMCA Standard 270-23 is $45 for AMCA members and $90 for non-members in printed or PDF format and $61 for AMCA members and $122 for non-members in both printed and PDF formats. To purchase a copy, click here.
