ABSTRACT:
An air inlet for a dust collector wherein a scroll inlet duct and an associated cylindrical duct are mounted on the top wall of the dust collector housing so that dust-laden gas flows into the scroll duct and through the cylindrical duct resulting in a rotational path of downwardly flowing gas within the cylindrical duct providing a centrifugal force on the gas so that when the dust-laden gas enters the collector housing it spreads outwardly toward the walls of the collector housing and downwardly resulting in a substantial cloud of uniform flow of dust-laden gas over the length and width of the collector housing to provide a uniform deposit of dust particles on the filters while precluding abrasion of the filter media. A perforated metal plate is positioned in the collector housing in proximity to the outlet of the cylindrical dust to facilitate the outward and downward flow of dirty gas in the collector housing.
