FILTER PERFORMANCE
The airflow capacity data published in Tables 8 & 9 repre-
sents blower performance WITHOUT filters. To determine the
approximate blower performance of the system, apply the fil-
ter drop value for the filter being used or select an appropri-
ate value from the Table 10.
NOTE: The filter pressure drop values in Table 10 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.
