NOTES:
1. Airflow expressed in standard cubic feet per minute (CFM) and in cubic meters per minute (m 3 /min).
2. Motor voltage at 115 V.
3. NR = Operation at this static pressure is not recommended.
FILTER PERFORMANCE
The airflow capacity data published in Table 18 represents blower per-
formance WITHOUT filters. To determine the approximate blower per-
formance of the system, apply the filter drop value for the filter being
used or select an appropriate value from the Table 19.
NOTE: The filter pressure drop values in Table 19 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 manufactur-
ers.
