Air Movement and Control Association Updates Air-Control-Devices Rating Publication
Air Movement and Control Association International Inc. has released AMCA Publication 511-21 (revised 12-22), Certified Ratings Program Product Rating Manual for Air Control Devices.
The publication outlines technical procedures and the proper presentation of data for the certification of air-control devices through the AMCA Certified Ratings Program. It is to be used in conjunction with AMCA Publication 11-22, Certified Ratings Program Operating Manual.
Used in general ventilation and air-conditioning systems, air-control devices include louvers, dampers, gravity ventilators, round spiral duct and transverse duct connections.

The publication is available for free download in PDF format. In printed format, the cost is $6 for AMCA members and $12 for non-members. For more information, visit amca.org.
