B01D46/2455 - CPC Classification

Classification description:

Filters or filtering processes specially modified for separating dispersed particles from gases or vapours; Particle separators, e.g. dust precipitators, using rigid hollow filter bodies characterised by the physical shape or structure of the filtering element; Honeycomb filters characterized by the geometrical structure, shape, pattern or configuration or parameters related to the geometry of the structure of the whole honeycomb or segments
