FILTER PERFORMANCE

NOTE: The filter pressure drop values in the “Filter Performance” table shown below 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 filter
manufacturer.

The airflow capacity data published in the “Blower Performance” table listed above represents blower performance
WITHOUT filters. To determine the approximate blower performance of the system, apply the filter drop value for the filter being used or select an appropriate value from the “Filter
Performance” table shown below.

APPLYING FILTER PRESSURE DROP TO
DETERMINE SYSTEM AIRFLOW
To determine the approximate airflow of the unit with a filter in place,
follow 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
pressure 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 corresponds to the intersection of the ESP column and
Model/Blower Speed row.

6.

If the total system static falls between ESP values in the table
(i.e. 0.58 w.c. (144 Pa), 0.75 w.c. (187 Pa), etc.), the static pressure may be rounded to the nearest value in the table determining the airflow using Step 5 or calculate the airflow by using the
following example.

Example: For a 130,000 BTUH (38.06 kW) furnace with 2 return
openings and operating on high-speed blower, it is found that total
system static is 0.58” w.c. To determine the system airflow, complete
the following steps:
Obtain the airflow values at 0.50 w.c. (125 Pa) & 0.60 w.c. (150 Pa)
ESP.
Airflow @ 0.50”: 2125 CFM (60.17 m3/min)
Airflow @ 0.60”: 2035 CFM (57.62 m3/min)
Subtract the airflow @ 0.50 w.c. (125 Pa) from the airflow @ 0.60
w.c. (150 Pa) to obtain airflow difference.
2035 - 2125 = -90 CFM (2.55 m3/min)
Subtract the total system static from 0.50 w.c. (125 Pa) and divide
this difference by the difference in ESP values in the table, 0.60 w.c.
(150 Pa) - 0.50 w.c. (125 Pa), to obtain a percentage.
(0.58 - 0.50) / (0.60 - 0.50) = 0.8
Multiply percentage by airflow difference to obtain airflow reduction.
(0.8) X (-90) = -72
Subtract airflow reduction value to airflow @ 0.50 w.c. (125 Pa) to
obtain actual airflow @ 0.58 inwc (144 Pa) ESP.
2125 - 72 = 2053
