Filter assembly and filter assembly manufacturing method
First Claim
1. A method for manufacturing a filter assembly for removing particles from an air stream, the filter assembly including at least one media pack in a frame structure, the at least one media pack being pleated and having a first open end and a second open end, the first open end and the second open end being opposing open ends, the method comprising:
- performing a first molding operation to seal the first open end and the second open end of the at least one media pack to establish a sealed first edge and a sealed second edge of the at least one media pack, respectively, the first molding operation including performing, for each open end of the first open end and the second open end,coupling the open end and a first molding compound layer to a pot, such that the open end is embedded in the first molding compound layer and the pot at least partially encloses the first molding compound layer and the open end, andcuring the first molding compound layer; and
performing a second molding operation to secure and seal the sealed first edge and the sealed second edge of the at least one media pack to at least one frame element of the frame structure, respectively, such that the pots of the sealed first edge and the sealed second edge are each secured and sealed to at least one frame element of the frame structure, respectively.

Abstract
The present invention relates to a filter assembly comprising at least one media pack arranged in a frame structure in which the at least one media packs is pleated and having opposing first and second open ends, and a corresponding method for manufacturing such a filter assembly for removing particles from an air stream. The method for manufacturing a filter assembly for removing particles from an air stream said comprises for each media pack sealing the first and second open ends in a first molding step, thereby providing a sealed first edge and a sealed second edge of each respective media pack, and subsequently arranging the at least one media pack in the frame structure and in a second molding step securing and sealing the sealed first edge and the sealed second edge, respectively, to at least one frame element of the frame structure.
