International Classification:

B03C 3/68

US Classification:

96 18, 96 55, 96 63

Abstract:

An air conditioning apparatus includes a cabinet having air inlet and outlet openings and an intense field dielectric air filtration system disposed in the cabinet between the inlet and outlet openings. The filtration system includes a field charging unit and a filter unit. The filter unit may be mounted for removal from the cabinet on spaced apart support brackets connected to the cabinet or to a frame of the field charging unit. Electrical contact elements may be supported by the support brackets for engagement with corresponding contact elements on the filter unit and charging unit for establishing electrical communication between a power supply and the charging unit and filter unit, respectively. A shorting bar is aligned with the contact members on the filter unit for discharging high voltage potential upon removal of the filter unit from the cabinet.
