ABSTRACT:
An electrically stimuated filter assembly includes a filter unit in which an air gap is maintained between the filter medium and electrodes disposed on opposite sides of that medium, thereby preventing degradation of filter efficiency by humid filtered fluid. The filter medium is a sheet-like member folded in multiple accordion pleats and disposed between two plate electrodes, one of which is grounded to the chassis, the other of which is at high voltage. The air gaps are established by insulative plastic combs having bases secured to the electrode plates and teeth projecting from the bases into troughs of the folded filter. The high voltage plate is on the downstream side of the filter and mounted recessed from the downstream opening by insulative tubes secured to both the filter housing and the high voltage plate. A precharger is disposed in the assembly upstream of the filter unit and includes plural individual high voltage wires suspended in mutually spaced parallel relation across the flow path. The precharger is housed in a grounded metal frame which is insulated from the wires.
