As a 25-year member of the Air Movement and Control Association, Stanley Fans has recognized the importance of providing the industry with accurate, straightforward and reliable published data for fan performance. Since 1975, we have proudly displayed the AMCA certified ratings seals on our air moving products. Fan sound and air performance testing for certification and new product R&D are achieved in our on-site lab, which includes an AMCA registered sound and airflow chamber, and a U.L. compliance motor testing facility. We invite you to come see why so many are making Stanley Fans their light industrial choice for all their ventilation demands.
