Abstract

An air cleaning system has a field charger comprising a plurality of bars comprising a conductive inner core and a non-conductive overmold, and a plurality of pins attached to the bars and extending out of the non-conductive overmold. The conductive inner core is molded over the plurality of pins, conductively connecting the pins, and the non-conductive overmold is molded over the conductive inner core. A method of manufacturing the field charger includes placing a plurality of metal pins in a mold, placing contact points in the mold, molding a conductive resin over at least a portion of the plurality of pins and contact points, molding an insulating resin over the inner core, plurality of pins, and contact points, wherein at least a portion of the pins and contact points extend from the non-conductive overmold, and mounting an earthplate to the conductive overmold.

Claims (14)

1. An air cleaning system, comprising:

a field charger, the field charger comprising:

a plurality of bars each comprising an octagonal profile and conductively connected to form a conductive inner core, wherein the conductive inner core comprises a non-conductive overmold molded over the conductive inner core; and

a plurality of pins embedded at least partially within and conductively connected to the conductive inner core and extending at least partially out of the non-conductive overmold;

at least one collection cell; and

a cabinet operable to house the field charger and the at least one collection cell.

2. The system of claim 1 , wherein the conductive inner core comprises a conductive plastic resin molded over the plurality of pins.

3. The system of claim 1 , wherein the non-conductive overmold comprises a nonconductive plastic resin.

4. The system of claim 1 , wherein the plurality of bars form a rectangular grid.

5. The system of claim 4 , wherein the rectangular grid is molded as one piece.

6. The system of claim 4 , wherein the bars are molded individually and then conductively connected to form the rectangular grid.

7. The system of claim 4 , wherein the rectangular grid is molded into subsections which are then conductively connected.

8. The system of claim 1 , wherein the field charger further comprises an earthplate coupled to the plurality of bars and configured to provide a ground connection for the field charger.

9. The system of claim 1 , wherein the non-conductive overmold comprises an octagonal profile concentric with the octagonal profile of the conductive inner core to reduce disruption of airflow over the field charger.
