AMCA 250

Certied Performance Data of Jet Fans:
Accuracy Leads to Safety
Before October 2018, AMCA allowed manufacturers to certify jet fan data with measured
airow methods. Then, AMCA released a new revision of AMCA Publication 211, Certied
Ratings Program Product Rating Manual for Fan Air Performance, and as the press release
stated,
“Following the October 2018 revision of AMCA Publication 211, jet fans no longer can be
certied using ANSI/AMCA Standard 210/ASHRAE Standard 51 [Laboratory Methods of
Testing Fans for Certied Aerodynamic Performance Rating] and ISO 5801 [Industrial Fans
— Performance Testing Using Standardized Airways] and must be certied using ANSI/
AMCA Standard 250 [Laboratory Methods of Testing Jet Fans for Performance].”
