B01D46/2448 - 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 parameters related to the physical properties of the honeycomb structure material of the adhesive layers, i.e. joints between segments
