ABSTRACT:
The invention is related to a framed filter media comprising a pleated filter media having a fluid inlet face and a fluid outlet face with peripheral sidewalls. The peripheral sidewalls of the pleated filter are attached to the frame generally by an adhesive. The frame is preferably a flexible strip frame formed into three or more (up to an infinite number if the sidewall sections(s) is formed into a circular filter frame) sidewall sections each having a substantially flat sidewall and at least two projecting filter retaining tabs which form a flange on a first face of the sidewall section for containing the filter along its peripheral sidewalls and any adhesive. A cross brace is also inserted within the filter retaining tabs which fits into at least one pleat of the framed pleated filter media. The cross brace fits into the space formed by the pleated filter media but is not in continuous contact with the filter media forming the pleat. The cross brace can be flexible and has end keys or projections for insertion into the filter frame flanges and attachment to the sidewall sections and/or the flange. In a particular embodiment, the cross brace has a continuous non-linear profile with an internal profiled groove with a mating surface, for insertion and locking of removable end keys or other items, such as handles and labels, which removable items have a profile that mates with, or locks the mating surface of the profiled groove.
