1. A dust filtering and collection system for use in moving granular material by air conveying, comprising:
a housing, said housing having an upper end and a lower end, and an air inlet on the housing positioned on the lower end of the housing, and an air outlet on the housing positioned on the upper end of the housing;
a dust filtering system within said housing, said dust filtering system comprising a transverse plate positioned in an upper interior of said housing, and a pod suspended from the transverse plate and extending downwardly into a lower interior of said housing, the pod comprising a header that encapsulates and supports upper ends of a plurality of filter tubes, and provided for holding the plurality of filter tubes suspended from the transverse plate;
a vacuum connection connected to said housing, said vacuum connection connecting with a blower assembly, said air inlet provided for delivery of dust laden air into the housing, such that when said blower assembly is actuated, said blower assembly provides for generating a vacuum within the housing that draws dust laden air into the air inlet on the housing, and drawing the dust laden air into the dust filtering system, to provide for cleansing of the air and passage to the blower for then aiding in the air conveyance of the granular material, during its functioning.
