Abstract: There is disclosed an industrial fan housing assembly, comprising: a plurality of scroll-liner sections configured to be assembled together to form a midsection of the industrial fan housing assembly, each scroll-liner section including a liner; wherein, each scroll-liner section includes side flanges to assemble the section to first and second fan housing scroll sideplates on either side. In an embodiment, at least two of the plurality of scroll-liner sections are identical and interchangeable, thereby allowing the identical and interchangeable sections to be assembled in one of a plurality of positions. Advantageously, the scroll-liner sections may be installed without welding or cutting, and may be individually removed for servicing or replaced when the lining is worn. The cost for operating and servicing and the fan housing assembly is significantly reduced.
