ABSTRACT:
A fluid filtering device in various embodiments is disclosed. The filter includes, in one embodiment, alternating layers (34', 36') of corrugated filter media which are rolled together and sealed at alternate ends by sealant (38, 42) forming longitudinal flutes and transverse inter-flute passageways. Further embodiments disclose filter packs (112, 212, 312) of alternating layers of oppositely oriented corrugated filter media. In one embodiment, flutes of successive layers are aligned in parallel. In an alternate embodiment flutes are aligned orthogonally. Unfiltered fluids enter tubular passages (44) for example, and must exit by adjacent passages either above, below or beside the flute of entry to exit the filter. Filtering occurs when the fluid crosses a sidewall of filter media.
