Abstract
An improved pickup or intake hood for use in regenerative air flow road and pavement sweeper vehicles includes at least one side auxiliary plenums and/or at least one side-to-side plenum adjacent the primary air flow compartment. The auxiliary plenums are attached by appropriate ducting into the regenerative air flow so that any fugitive air and or dust flows from the primary air flow compartment are captured in the auxiliary plenums to minimize fugitive air and/or dust flows into the ambient atmosphere. Dust conduits from shrouded gutter brooms enter a manifold box to allow dust-entrained air flows from one or both gutter brooms to enter into the regenerative air flow to capture dust generated by the gutter brooms.
