Claim 10

The dust collector of claim 7 wherein: said filter elements are substantially perpendicular to said downward sloping surface of said lowermost portion, wherein ends of said filter elements lie substantially flush against same.

Claim 11

The dust collector of claim 8 wherein: said downward sloping surface has additional openings aligned with and corresponding to said ends of said filter elements.

Claim 12

The dust collector of claim 9 further comprising: an interior wall of planar construction mounted to said housing and parallel to but spaced from said downwardly sloping surface with said filter elements being in contact with and located therebetween.

Claim 13

The dust collector of claim 10 wherein: said interior wall has openings aligned with and corresponds to said additional openings in said downward sloping surface.

Claim 14

The dust collector of claim 7 further comprising: mounting means for mounting said filter elements wherein said mounting means includes groups of three cantileveredly supported rod elements with said rod elements substantially parallel to each other in a generally triangular formations.

Claim 15

The dust collector of claim 7 further comprising: deflector means for deflecting air moving in said first direction positioned between said entrance opening and said filter elements.

Claim 16

A dust collector comprising: a housing having an upper wall, side walls depending from said upper wall, a lowermost portion having at least one generally downward sloping surface, one of said side walls having an entrance opening, and one of said side walls having an exit opening in a location wherein said entrance opening and said exit opening are of generally the same elevation; filtering means mounted within said housing and operable to filter air moving in a first direction therethrough, said filtering means including at least two substantially parallel rows of filter elements including a lowermost row, wherein filter elements within said lowermost row are vertically staggered with respect to all filter elements within an adjacent row located immediately thereabove, wherein said filter elements are mounted in a generally inclined direction with respect to said upper wall, wherein all of said filter elements are mounted partially within said lowermost portion of said housing; pulsing means operably associated with said filtering means and operable to direct pulses of pressurized air flow in a direction opposite from said first direction and of a magnitude greater than said air moving in said first direction through said filter means dislodging foreign particulate matter from said filter means, said lowermost portion being positioned to receive said foreign particulate matter from said filter means as said pulsing means dislodges same; and, transfer means in said lowermost portion of said housing for transferring said particulate matter from within said lowermost portion to a location exterior to said housing.

Claim 17
