Filter structure for removing contaminants from stream of fluid
First Claim
Patent Images
1. A filter structure for removing contaminants from a stream of fluid, comprising:
- a generally rectangular front filter portion and a generally trapezoidal rear filter portion;
said front filter portion including front frame structure supporting a first front filter and a second front filter in substantially parallel spaced relation to one another;
said front frame structure, said first front filter, and said second front filter substantially surrounding a front clean air passageway;
said rear filter portion including rear frame structure supporting a first rear filter and a second rear filter in substantially divergent spaced relation with one another;
a less spaced end of said first rear filter and said second rear filter being proximal said front filter portion and a more spaced end of said first rear filter and said second rear filter being distal said front filter portion;
said rear frame structure, said first rear filter, and said second rear filter substantially surrounding a rear clean air passageway;
wherein said rear clean air passageway is in communication with said front clean air passageway and in communication with a filter structure outlet between said first rear filter and said second rear filter proximal said more spaced end of said first rear filter and said second rear filter.

9. A filter structure for removing contaminants from a stream of fluid, comprising:
-
a front filter portion defining a front clean air passageway therein, said front filter portion having a first front filter and a second front filter flanking said front clean air passageway, said first front filter and said second front filter being at a first orientation relative to one another; a rear filter portion downstream of said front filter portion, said rear filter portion defining a rear clean air passageway therein, said rear clean air passageway being in flow communication with said front clean air passageway, said rear filter portion having a first rear filter and a second rear filter flanking said rear clean air passageway, said first rear filter and said second rear filter being at a second orientation relative to one another; wherein said second orientation is distinct from said first orientation; and wherein said second orientation is a diverging orientation wherein said first rear filter and said second rear filter are more proximal one another adjacent said front filter portion. - View Dependent Claims (10, 11, 12, 13, 14)

15. A fluid filtering system, comprising:
-
a plurality of filter structures interposed between an unfiltered fluid intake area and a filtered fluid output area; said filter structures having an air passageway therein flanked by a first side filter portion and a second side filter portion, said air passageway being in communication with said filtered fluid output area; wherein said first side filter portion and said second side filter portion allow communication of fluid therethrough both into and out of said air passageway; said first side filter portion and said second side filter portion having a substantially parallel orientation with respect to one another along a first length and having a substantially diverging orientation with respect to one another along a second length; wherein said first length is more distal said filtered fluid output area than said second length; and wherein along said second length said first side filter portion and said second side filter portion become more divergent as they become more proximal said filtered fluid output area. - View Dependent Claims (16, 17, 18, 19, 20)
