5 FILTE PEFOMANE 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. 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. EOMMENDED FILTE SIZES Input/Output BTU/H FM abinet Size Side eturn Filter in.

8 APPLYIN FILTE PESSUE DOP TO DETEMINE SYSTEM AIFLOW 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, 0.60, 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, 0.75, 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 120,000 Btuh 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: 1. Obtain the airflow values at 0.50" & 0.60" ESP. 0.50": 2285 FM 0.60": 2175 FM 2. Subtract the 0.50" from the 0.60" to obtain airflow difference = -110 FM 3. Subtract the total system static from 0.50" and divide this difference by the difference in ESP values in the table, 0.60" ", to obtain a percentage. ( ) / ( ) = Multiply percentage by airflow difference to obtain airflow reduction. (0.8) x (-110) = Subtract airflow reduction value to 0.50" to obtain actual 0.58" ESP = 2197 AESSOIES ONENTI VENT TEMINATION - 1T0302 (2") 1T0303 (3") For use through rooftop, sidewall.
