FILTER PERFORMANCE

The airflow capacity data published in the "Blower Perfor-
mance" table listed above represents blower performance
WITHOUT filters. To determine the approximate blower per-
formance of the system, apply the filter drop value for the fil-
ter being used or select an appropriate value from the "Filter
Performance" table shown below.
NOTE: The filter pressure drop values in the "Filter Perfor-
mance" 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.
