1. A vertical drop product cleaner for separating fines and/or foreign matter from dry, free-flowing, granular product, the cleaner comprising: a housing;a separation plenum formed by spaced inlet and outlet manifolds within the housing;the inlet manifold including at least two louvers defining an air inlet channel therebetween to provide a flow path for air into the separation plenum, at least one of the louvers including an upper inlet lip, a lower inlet lip, and a vertical louver member, the upper inlet lip and lower inlet lip each extending at an angle off of the vertical louver member, and the at least one louver further defining a plurality of apertures configured to allow airflow therethrough, the plurality of apertures being included in the vertical louver member; andthe outlet manifold defining at least one air outlet providing a flow path for air out of said separation plenum. 2. The cleaner of claim 1, wherein the inlet manifold includes a series of louvers each defining a plurality of apertures. 3. The cleaner of claim 1, wherein the plurality of apertures are arranged in a series of rows and columns. 4. The cleaner of claim 1, wherein the plurality of apertures comprise perforations. 5. The cleaner of claim 1, wherein the plurality of apertures comprise fenstration. 6. The cleaner of claim 1, wherein the at least one louver includes between 20% and 50% open area defined the by the plurality of apertures. 7. The cleaner of claim 1, wherein at least one of the upper inlet lip and the lower inlet lip further include the plurality of apertures. 8. The cleaner of claim 1, wherein the upper inlet lip, the lower inlet lip, and the vertical louver member each include the plurality of apertures. 9. The cleaner of claim 1, wherein the outlet manifold includes at least one outlet louver, the outlet louver being substantially free from apertures. 10. A method of operating a vertical drop product cleaner comprising the steps of: providing a vertical drop product cleaner having a separation plenum formed by spaced inlet and outlet manifolds, the inlet manifold including at least two louvers defining an air inlet channel therebetween, at least one of the louvers including an upper inlet lip, a lower inlet lip, and a vertical louver member, the upper inlet lip and lower inlet lip each extending at an angle off of the vertical louver member, and the at least one louver further defining a plurality of apertures in the vertical louver member; andmoving air through the air inlet channel and the plurality of apertures. 11. The method of claim 10, wherein the outlet manifold includes at least two outlet louvers defining an air outflow channel therebetween, the at least two outlet louvers being substantially free from apertures, further comprising the step of moving air through the air outflow channel. 12. The method of claim 10, wherein the plurality of apertures are arranged in a series of rows and columns. 13. The method of claim 10, wherein the at least one louver includes between 20% and 50% open area defined the by the plurality of apertures. 14. The method of claim 10, wherein the upper inlet lip, the lower inlet lip, and the vertical louver member each include the plurality of apertures, and moving air through the plurality of apertures comprises moving air through the plurality of apertures in each of the upper inlet lip, the lower inlet lip, and the vertical louver member.
