Air Movement and Control Association (AMCA) International Inc. announced during its 2016 Annual Meeting in Washington, D.C., that the first sand louvers have been certified for wind-driven-sand rejection in accordance with the AMCA Certified Ratings Program.
Sand louvers protect air systems from wind-driven sand, which can enter mechanical rooms and foul equipment and clog air filters ahead of their normal service life. Certifying sand louvers enables the comparison of manufacturers' ratings for sand rejection based on test data in accordance with ANSI/AMCA Standard 500-L (Rev. 2015), Laboratory Methods of Testing Louvers for Rating.
Ratings tests for sand rejection are being conducted by Thomas Bell-Wright International Consultants in Dubai, which is accredited by AMCA International as an independent laboratory. Certification of the test data was performed by AMCA staff in compliance with AMCA Publication 511-10 (Rev. 2015), Product Rating Manual for Air Control Devices.
