An inkjet nozzle device includes a main chamber having a floor, a roof and a perimeter wall enclosing the main chamber. The main chamber includes: a firing chamber having a nozzle aperture defined in the roof and a bar heater for ejection of ink through the nozzle aperture; an antechamber for supplying ink to the firing chamber, the antechamber having a chamber inlet defined in the floor; and a baffle plate extending parallel with the bar heater, which partitions the main chamber to define the firing chamber and the antechamber. The nozzle device has mirror symmetry about a symmetry plane extending perpendicular to the longitudinal axes of the bar heater and the baffle plate.
