Recently revised AMCA Publication 802, Industrial Process/Power Generation Fans: Establishing Performance Using Laboratory Models, outlines methods used by manufacturers to determine the performance of full-size industrial-process and power-generation fans. Changes to it include:

  • Updated terminology (fan total pressure vs. fan stagnation pressure).
  • Updated I-P formulas consistent with ANSI/AMCA Standard 210/ASHRAE Standard 51, Laboratory Methods of Testing Fans for Certified Aerodynamic Performance Rating.

Produced by the Air Movement and Control Association Intl., Publication 802-19 provides detailed insight into variables that influence fan ratings and establishes rules to be used to convert performance from one fan to a geometrically similar fan. In addition, it defines dimensional tolerances that must exist for two fans to be considered geometrically similar.
