NOTE: (1) Data Based on Bottom Only or One Side return.
(2) Data Based on Both Sides or Bottom plus One Side.
(3) 100J20 Reduce airflow by 5% if Bottom Only return.
(4) 125J20 Reduce airflow by 5% if Bottom Only return.
(5) Gray area is above maximum temperature rise range.
# CFM − Cubic Feet Per Minute airflow. Filter required for each
return−air inlet.
Airflow performance includes 1” (25.4mm) washable [600 FPM (3.0
M/s) max] filter media.
MAX CFM for Factory Washable Filters

Max CFM based on 600 FPM (3.0 M/s)
NOTE: Disposable filters are typically rated at 300 FPM (1.5 M/s). These filters
only allow half the airflow when compared to 600 FPM (3.0 M/s) filters.
