Test context and interpretation

* Manufacturer maximum-rated airflow marker. This does not establish your installed airflow.

Printed initial resistance; additional test conditions not recovered.

Filter differential pressure is only one part of system resistance. These points do not establish your delivered airflow, fan energy use, loaded performance or safe service interval. No interpolation is applied.
