1Unit resistance is based on a wet evaporator coil and clean filters.

2Available 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:

RPM range for standard factory-mounted drive components.

Exceeds the output limitation of the standard factory-mounted blower motor.
