[Ma, Shane, Michael]
HEPA fan air flow measurements are done with the fans sitting on their side in the lab, and the anemometer being 24in away from the filter face of the fan. Per company's documents, we need to replace the filter if the air flow velocity drops under 38-45 fpm for the medium settings.)

All numbers are in fpm unit. The measurement for each unit is done twice in front of the fan positions. |
