De-dusting is a process that mainly involves using screening and other pneumatic means to remove fine impurities such as dust. De-dusting and fume extraction systems are installed in order to capture fugitive fumes and dust emitted in furnaces, during various processes, and during handling of materials.

De-dusting systems are usually custom made according to a specific project and design. However, they mainly consist of butterfly dampers (both automatic and manual), elaborate duct work at appropriate locations, suction hoods at fume/dust generating points, casing entry, a modular, offline, a centrifugal ID fan, pulsejet bag filter, and a self-supported stack.

De-dusting is not only about the corporate image but dust also lowers the quality especially in manufacturing industries. Also, Environmental protection has become a vital social issue.
