Abstract
An air filtering unit for a factory includes: an entry duct; a flow expander section fluidly connected with the entry duct, the flow expander section including a flow distribution unit and a flow velocity reduction unit; a filter unit fluidly connected with the flow expander section, the filter unit having a plurality of filter bags, the filter bags being suspended from a tube sheet; and an exit duct fluidly connected with the filter unit. The flow distribution unit includes a series of flow distribution members positioned along a flow path, the flow distribution unit located and configured to substantially equally distribute an airstream along the length of the flow axis into a plurality of divided substreams. The flow velocity reduction unit includes a plurality of flow reduction members, each of the flow reduction members positioned and configured to confront at least one of the divided substreams and reduce the flow velocity thereof.
