EnergyPlus requires a single loop (obj AirLoopHVAC / PlantLoop / CondenserLoop) to be balanced: if you supply 6000 CFM you also need to return 6000 CFM. There is no other possibility.
For Exhaust fan look at "System Availability Manager Coupling Mode" and "Balanced Exhaust Fraction Schedule Name" but be aware that this obj takes only into account the Power/Energy of the fan, not its thermal effect on the zone air thermal balance
