The Air Movement and Control Association (AMCA) International has revised AMCA Publication 802, Industrial Process/Power Generation Fans: Establishing Performance Using Laboratory Models.
While both belt and direct drive fans have been around for a long time, the mainstay fan for most industrial fan applications under 250 hp has been the belt drive fan.
Throughout 2019, the Air Movement and Control Association (AMCA) is making ANSI/AMCA Standard 208, Calculation of the Fan Energy Index, available for download at no cost in its online store.
