We are pleased to announce that ANSI/AMCA Standard 280, Test Methods for Wind Resistance and Impact Resistance for Fans and Ventilators, was officially published on February 23, 2026.
Current wind-resiliency test standards for fans and ventilators were originally developed for windows and doors and do not accurately reflect the structural demands of high-wind events. Their inconsistent application has led to variability in testing procedures and unclear pass/fail determinations.
ANSI/AMCA 280 was developed specifically for fans and ventilators to address these challenges. The standard incorporates defined large missile impact locations along with lateral and uplift load tests that better simulate real-world conditions. The result is a more consistent and relevant methodology that supports clearer compliance pathways, including for manufacturers pursuing Miami-Dade Notice of Acceptance (NOA) listings.
We thank the committee members and contributors whose expertise and dedication made this important milestone possible.
