The subject matter disclosed herein relates to air filtration systems. More specifically, the subject disclose relates to field wires for electrically enhanced air filtration systems.
In air filtration systems, for example, electrically enhanced air filtration systems, electrostatic filters installed in the systems collect impurities in an airflow through the system before the airflow is circulated through a space such as a home or other building. The systems utilize an electrically-charged ionization array and an electrically-charged field wire located across the airflow upstream of the electrostatic filter. These components are intended to increase the effectiveness of collection of the impurities by the media filter.
Typically, the field wire is energized to first voltage by the power supply and the ionization array is energized to a second voltage by the power supply. Thus the power supply must produce two voltages, which are also regulated by the power supply.
