    摘要: A dust filtering and collection system for filtering dust and other particles from an air stream generally being used for conveying granular material into or from a bulk tank, with the filtering system designed to incorporate structure, such as a specially designed grommet, for holding a porous filter tube for filtering out such dust particles, with a grommet having structure to provide for its interlocking and engagement with and through an aperture in a transverse plate within the system. The grommet has an upper flange, that engages the upper surface of the transverse plate, and has an inner flange for engagement with the upper edge of the filter tube, while the bottom of the grommet has resilient fingers and associated detents for engaging the bottom of the transverse plate, to furnish an interlocking of the grommet, with its supported filter tube, onto and through the transverse plate.
