NOTES:

1.Airflow expressed in standard cubic feet per minute (CFM) and in cubic meters per minute (m3/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.

TABLE 19: Filter Performance - Pressure Drop Inches W.C. and (kPa)

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.
