1. The Airflow Descriptor is the two digits following the "D" in the model number; e.g. "20" is the Airflow Descriptor for G2080CT100V20C.
2. Areas and dimensions shown for permanent filters are based on filters rated at 600 feet per minute face velocity.
3. Typical filter sizes are shown, however, any combination of filters whose area equals or exceeds the minimum area shown is satisfactory.
