NOTES:
1. Airflow expressed in standard cubic feet per minute (CFM) and in cubic meters per minute (m
2. Return air is through side opposite motor (left side).
3. In order to stay within the velocity rating the filters, airflows above 1800 CFM (50.97 m
4. Motor voltage at 115 V.
5. NR = Operation at this static pressure is not recommended.
FILTER PERFORMANCE
The airflow capacity data published in Table 15 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 16.
