Abstract
A filtration system has a main filter assembly having a frame and filter media comprising pleated sections arranged in a row in V shapes within the frame. The filter media is spaced from an upstream face of the frame a distance sufficient to prevent blinding of the filter media by an upstream filter media, thereby eliminating a filtration stage and reducing the volume of the filtration system. Filter media alignment members disposed within the frame assist in holding the filter media sections in alignment within the frame. In another embodiment, flexible strips of edge banding, preferably of a filter material, are affixed to adjacent upper and lower longitudinal edges of the sections of the filter media. The edge banding minimizes pressure drop across the filter and is simpler and less costly to manufacture.
