FILTER PERFORMANCE
The airflow capacity data published in Table 15 represents blower per-
formance WITHOUT filters. To determine the approximate blower per-
formance of the system, apply the filter drop value for the filter being
used or select an appropriate value from the Table 16.
NOTE: The filter pressure drop values in Table 16 are typical values for
the type of filter listed and should only be used as a guideline.
Actual pressure drop ratings for each filter type vary between fil-
ter manufacturers.
* Washable Fibers are the type supplied with furnace (if supplied).
APPLYING FILTER PRESSURE DROP TO
DETERMINE SYSTEM AIRFLOW
To determine the approximate airflow of the unit with a filter in place, fol-
low the steps below:
1. Select the filter type.
2. Select the number of return air openings or calculate the return
opening size in square inches to determine the proper filter pres-
sure drop.
3. Determine the External System Static Pressure (ESP) without the
filter.
4. Select a filter pressure drop from the table based upon the number
of return air openings or return air opening size and add to the
ESP from Step 3 to determine the total system static.
5. If total system static matches a ESP value in the airflow table (i.e.
0.20 w.c. (50 Pa), 0.60 w.c. (150 Pa), etc,) the system airflow cor-
responds to the intersection of the ESP column and Model/Blower
Speed row.
