* ESP (External Static Pressure) .5" WG is at furnace outlet ahead of cooling coil.
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 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.
NOTE: The filter pressure drop values in the “Filter Perfor-
mance” table shown are typical values for the type of filter
listed and should only be used as a guideline. Actual pres-
sure drop ratings for each filter type vary between filter manu-
facturer.
