Unit resistance is based on a dry evaporator coil and clean filters. 2. Available static pressure in IWG to overcome the resistance of the duct system and any accessories added to the unit. Refer to the blower motor and drive table and the accessory static resistance table for additional information. 3. Motors can be selected to operate into the service factor because they are located in the moving air stream, upstream of any heating device. units with steam or hot water coils are the only exception. On these units, the BHP must not exceed the nominal HP rating of the motor.
