EN Dust occurring in the atmospheric air constitutes a difficult and important matter within environmental protection. Consequently, the relevant solutions aiming to eliminate or reduce the emissions of such pollutants are being sought for. It is implemented by the application of the relevant exhaust gases purification installations as well as by controlling the dust emissions. While selecting or designing the dust removal devices one should consider the estimated quantities and types of dusts, the places of their intended usage, material durability, tightness of connections. In the course of numerous production processes it is necessary to use precise, multi-stage air purification. In order to perform the preliminary dust removal, the simplest devices, like gravity settling chambers, can be successfully applied. The following chapter presents the theoretical fundamentals of dust removal process as well as the methods for dust removal from the air and exhaust gases taking advantage of various physical mechanisms. On top of that, designing solutions for the devices applied to dust removal are going to be presented so are the outcomes of the research regarding the modernisation of a classic chamber separator. The attempts included the changes in the design by replacing a cuboidal chamber with a cylindrical one. In order to intensify the process, swirl motion phenomenon has been taken advantage of. This allowed to obtain satisfactory efficiency values by using a set of basic physical phenomena.
