The July 2009 revision provides additional requirements for the Sound Performance Licensing of Air Curtain Units. Sound performance ratings for Air Curtain Units are needed. The AMCA International Certified Ratings Program for Fan Sound Performance included Air Curtain Units. However, the specific test setup for Air Curtain Unit (ACU) sound testing was not specified. In order to allow the buyer or specifier of ACUs to fairly compare sound rating information, a standardized test setup was needed. In general, the Figure 1 test setup found in ANSI/AMCA 300-08 will be used. A new annex in AMCA 311 will describe the specific setup requirements for an ACU. The requirements of ANSI/AMCA 300-08 will continue to be met.
