Bergman, W

This patent describes a recirculating electric air filter comprising: a hollow air permeable inner high voltage electrode connected to a DC high voltage source; a removable filter material surrounding the inner electrode; an electrically grounded outer air permeable ground electrode mounted around, spaced apart from and electrically insulated from the inner electrode and containing the filter material therebetween. The outer electrode is formed of segments moveably connected together to allow easy disassembly for removing the filter material; the inner electrode, filter material, and outer electrode defining an air flow path therethrough between the exterior of the outer electrode and interior of the inner electrode; an insulated sealing flange at one end of the electrodes for providing a seal between the inner and outer electrode; an insulated plate at the opposite end of the electrodes for providing a seal across the end of the air filter; a base having the electrodes mounted thereto and containing a blower means for drawing air out from or blowing air into the inner electrode.
