NOTES:

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

3

/min).

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

3

/min) require either return from two sides or one side plus bottom.

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 17 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 18.

NOTE: 

The filter pressure drop values in Table 18 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.
