Baghouse is a common term for the collection device that uses fabric bags to filter particulate out of a gas stream. The filter bags are mounted on a tubesheet and enclosed in a sheet-metal housing. The housing is visible and the single word baghouse is easy to pronounce, but filtration is more technically descriptive of the process. Frequently, the term fabric filtration is used, partly to be technically accurate and partly to distinguish the technology from water filtration. While filtration of particles from air commonly employs fabric bags as the filter media, porous ceramic candles and paper cartridges also are used to clean gas streams. Finally, a fabric filter baghouse system includes the bag cleaning system, dust collection hoppers, and dust removal system, so the total system involves more than just filtration.
