Abstract
A polarized media electronic air filter assembly has an electronics box mounted along one side by a slid-in fit into an open, receiving channel. Arcing between screens is reduced by using a relatively resistive material for at least one of the screens exposed to arcing.
Claims5
An electronic air filter comprising:
- a) a frame having an electronics-support side;
- b) external polarizing screens contained within said frame;
- c) polarizable dust-trapping media contained between the external screens;
- d) a central screen contained within the external polarizing screens and separated from said external polarizing screens by said dust-trapping media;
- e) a channel with an inner volume mounted along said electronics-support side of the frame, said channel not extending the full length of said electronics-support side;
- f) a high voltage supply electronics box containing a high voltage power supply having a protruding end portion,
- wherein said protruding end portion is dimensioned to interfit within the inner volume of the channel so that the channel/box combination collectively acts as an extension to the filter frame, providing the filter with the shape of a completed rectangle so that, when it is installed in an air handling unit, it will seal properly, directing air to pass only through the filter medium.
