An air transporting-conditioning device comprising: a housing, an emitter
electrode configured within the housing, a collector
electrode configured within the housing and positioned downstream from the emitter
electrode, a removable trailing electrode configured within the housing and downstream of the collector electrode, a first
voltage source electrically coupled to the emitter electrode and the collector electrode, wherein the first
voltage source energizes the emitter and collector electrodes to create a flow of air downstream from the emitter electrode to the collector electrode, and a second
voltage source electrically coupled to the trailing electrode. The second
voltage source is independently and selectively controllable of the first
voltage source. The housing includes a grill, whereby the trailing electrode is removably secured to the grill. Alternatively, the trailing electrode is removable from the housing by other means or fixed in the housing.
