Abstract

An electrode support for an electrode of an electrically-enhanced air filtration system includes a conductor extending through the electrode support and electrically connectible to the electrode and to a power supply. An insulative layer is located around the conductor and the electrode support is configured to position the electrode in a frame of the air filtration system. An air filtration system includes a frame directing an airflow through the air filtration system and an electrode located in the frame. An electrode support positions the electrode in the frame and includes a conductor extending through the electrode support and electrically connected to the electrode and an insulative layer located around the conductor. An electrical power supply is electrically connected to the conductor to provide electrical power to the electrode.

First claim

The invention claimed is:

1. An electrode support for an electrode of an electrically-enhanced air filtration system comprising:
a conductor extending through the electrode support and electrically connectible to the electrode and to a power supply;
an insulative layer disposed around the conductor;
the electrode support configured to position the electrode in a frame of the air filtration system; and
a plurality of support ribs configured to engage with a plurality of connector ribs disposed at one of the frame or an access door to create a an electrical connection with a surrounding connector having a long path length, the plurality of support ribs arranged as a plurality of concentric rings configured to engage with the plurality of connector ribs arranged as a plurality of concentric rings.

2. The electrode support of claim 1 , wherein the electrode support includes one or more sheds extending radially outwardly from a central axis of the electrode support.

3. The electrode support of claim 2 , wherein the one or more sheds include one or more of spokes, waves or undulations.

4. The electrode support of claim 1 , wherein the conductor is electrically connectible to the electrode via a mechanical fastener.

5. The electrode support of claim 1 , wherein the conductor is electrically connectible to the power supply via a spring-loaded plunger connection.

6. An air filtration system comprising:
a frame directing an airflow through the air filtration system; and
an electrode disposed in the frame;
an electrode support to position the electrode in the frame including:
a conductor extending through the electrode support and electrically connected to the electrode;
an insulative layer disposed around the conductor; and
a plurality of support ribs configured to engage with a plurality of connector ribs disposed at one of the frame or an access door to create a an electrical connection with a surrounding connector having a long path length, the plurality of support ribs arranged as a plurality of concentric rings configured to engage with the plurality of connector ribs arranged as a plurality of concentric rings; and

an electrical power supply electrically connected to the conductor to provide electrical power to the electrode.

7. The air filtration system of claim 6 , wherein the plurality of connector ribs are disposed at a connector secured to the frame.

8. The air filtration system of claim 7 , wherein the connector is formed from one of silicone or EPDM rubber.

9. The air filtration system of claim 6 , wherein the one or more of the plurality of connector ribs and the plurality of support ribs are tapered along their length.

10. The air filtration system of claim 6 , wherein the plurality of support ribs and the plurality of connector ribs form a seal therebetween.

11. The air filtration system of claim 10 , wherein the seal is formed between an outermost support rib of the plurality of support ribs and an outermost connector rib of the plurality of connector ribs.

12. The air filtration system of claim 6 including a spring-loaded plunger electrical connection between the electrode and the power supply.

13. The air filtration system of claim 6 , wherein the electrode support includes one or more sheds extending radially outwardly from a central axis of the electrode support.

14. The air filtration system of claim 13 , wherein the one or more sheds include one or more of spokes, waves or undulations.

15. The air filtration system of claim 6 , wherein the conductor is electrically connectible to the electrode via a mechanical fastener.
