1
Unit resistance is based on a wet evaporator coil and clean filters.
2
Available static pressure in IWG (Pa) to overcome the resistance of the duct system and any accessories added to the unit. Refer to Table 6 for the resistance of these
accessories and to Table 7 for additional motor and drive data
NOTE: Motors can be selected to operate into the service factor because they are located in the moving air stream, upstream of any heating device.
LEGEND:
TABLE 5 - BLOWER PERFORMANCE
RPM range for standard
factory-mounted drive components.
Exceeds the output limitation of the standard
factory-mounted blower motor.
