Abstract: Structures for V-bank electrostatic air filters are described. The V-bank air filters are assembled from two side panels, perforated top and bottom plates, a narrow end wall and an open wide end for the intake of air to be filtered. A pair of enclosure plates are pivotally mounted to the side panels in a parallel relationship to the respective top and bottom plates to form a pair of rectangular enclosures for respectively supporting electrostatic filter pads. The enclosure plates pivot open for removal and replacement of the filter pads. The side panels, top and bottom plates and rear wall are made from sheet metal blanks using cutting, bending and stamping processes. The enclosure plates are made from sheet metal blanks or welded wire structures. The advantage is that the structures are manufactured using simple automated processes and are quickly assembled without sub-assembly, thus time and labour are saved and costs are reduced.
