Structures for electrostatic V-bank air filters

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.

Description

technical field

[0001] The present invention relates to an air filter, and more particularly, to a structure useful for a V-group electrostatic air filter. Background technique

[0002] Public awareness of environmental issues has continued to increase over the past few decades. Therefore, the public now needs a high-quality environment with clean air to live, work and rest. Various filtration systems are used in residential and commercial buildings to improve air quality. One type of air filter commonly used is the "bag" or "bag" filter, which is designed to provide as large a filter surface area as possible for the air flow path. Yet another type of filter for this purpose is the V-group filter, which has two filter surfaces in the air flow passage compared to a flat filter.

[0003] Bag filters are known to pack a plurality of filters in a suitably shaped housing. Since the installation of these disposable filter packs must be connected to each other by a sewing or gl...
