Airflow

 

1.  CFM in chart is without filter(s). Filters do not ship with this furnace, but must be provided by the installer. If the furnace requires two return filters, this 

chart assumes both filters are installed.

2.   For most jobs, about 400 CFM per ton when cooling is desirable.
3.   INSTALLATION and/or BLOWER SPEED CAN BE ADJUSTED TO OBTAIN TEMPERATURE RISE WITHIN THE RANGE SPECIFIED ON THE RATING 

PLATE.

4.   The chart is for information only. For satisfactory operation, external static pressure must not exceed value shown on rating plate. The shaded area 

indicates ranges in excess of maximum external static pressure allowed when heating. The data for 0.6” w.c. to 0.8” w.c. is shown for air conditioning 

purposes only.

5.   At higher altitudes, a properly derated unit will have approximately the same temperature rise at a particular CFM, while the ESP at that CFM will be 

lower.
