4. Motor voltage at 115 V. 5. NR = Operation at this static pressure is not recommended. Johnson Controls Unitary Products 277805-YTG-A-1106 FILTER PERFORMANCE 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. FILTER PERFORMANCE - PRESSURE DROP INCHES W.C.

Air velocity through throwaway type filters may not exceed 300 feet per minute. All velocities over this require the use of high velocity filters. 2. Air flows above 1800 CFM require either return from two sides or one side plus bottom.

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.
