ARLINGTON HEIGHTS, Illinois, United States, 5 May 2023: Air Movement and Control Association (AMCA) International releases AMCA Publication 211-22 (Rev. 01-23), Certified Ratings Program Product Rating Manual for Fan Air Performance. Making the announcement through a Press release, AMCA said that superseding AMCA Publication 211-22, AMCA Publication 211-22 (Rev. 01-23) prescribes technical procedures for rating fans and axial impellers for air performance to be used in connection with the AMCA Certified Ratings Program (CRP).

AMCA Publication 211-22 (Rev. 01-23) coordinates the AMCA CRP with the US Department of Energy’s (DOE’s) requirements for large-diameter ceiling fans (LDCF). Changes were made to sections 9.11, ‘Rating method N: Large-diameter ceiling fans’, and 22, ‘Product Ratings Requirements for Large-Diameter Ceiling Fans’, AMCA said. Additionally, the title of Section 20 was changed, AMCA added.

According to AMCA, Changes in 211-22 (Rev. 01-23) include:

• The addition of the DOE definition of large-diameter ceiling fan
• The addition to the list of rating requirements the number of available fan speeds, the capability of reverse flow and, if applicable, whether fan-speed controls are separate from lighting controls
• The allowance of conservative standby-power-consumption ratings
• The addition of testing voltage requirements for LDCF regulated by the DOE and having polyphase electricity

AMCA said Publication 211-22 (Rev. 01-23) is available in PDF format free of charge.
