Abstract
An air filter includes a stack of filter discs formed with contacting faces having surface formations defining filtering passageways between adjacent discs for removing solid particles from the air passing through the stack. The filter discs in the stack further include electrodes spaced from each other axially of the stack and connectable to a voltage source for producing an electrical field attracting solid particles towards the discs to thereby enhance removal of the solid particles from the air passing through the stack. The filter discs in the stack include a first plurality of insulating discs composed of insulating material, and a second plurality of electrode discs composed of electrically-conductive material, with the electrode discs separated from each other by at least one insulating disc.
