Crimp seal pleated filter assembly.

摘要

A crimp seal pleated filter assembly having a base (20), a frame (40) and a filter media (60), including a plurality of pleats (66). When assembled, the pleats (66) of the filter media (60) are uniformly aligned within the assembly 10 and are secured therein by crimp sealing the filter media ends (62) between interlocking projections (30) 50 on the sides (23) of the base (20) and side walls 43 of the frame. Outboard end flaps (68) of the filter are crimp sealed and encapsulated between side blades (26) of the frame (20) and the front wall (42) and back wall (44) of the frame, minimizing flaking or chafing of fibers from the filter (60).
