摘要： An air filtration system for use in capturing fugitive dust in industrial sweeping operations includes a hopper having internal structure for causing change in the direction of flow of suction air which enters the hopper along with debris collected during an industrial sweeping operation. A plurality of filters is disposed within the hopper for filtering the suction air, each one of the plurality of filters having filter media therein which can be repeatedly purged for cleaning and continuous reuse thereof. Structure is included for providing repeated purging blasts of air to the plurality of filters, and structure is associated with each one of the plurality of filters for causing the purging blasts of air to clean substantially the entire filter media of each one of the filters. The system also includes structure for creating suction air which is pulled through the hopper and the filters disposed therein before exit of the suction air from the hopper substantially free from debris, particulate matter and fugitive dust which is collected by the system.
