Abstract: The invention relates to a filter (28) for removing particulate matter from a gaseous fluid (12) having a filter element (30) with a filter media (32) which is arranged in a ring-shaped fashion around the longitudinal axis (34) thereof and a pre-separator sleeve (40) which seats on the filter element (30) and which has several perforations (52). On an outside surface (42) of the pre-separator sleeve (40), there is arranged at least one guide vane (44) which extends radially outwards from the pre-separator sleeve (40). The guide vane (44) is wound around the pre-separator sleeve (40) in a helical fashion to thereby further increase the separating efficiency of the pre-separator sleeve (40). The invention further relates to a cyclone filter system with an aforesaid filter (28).

Abstract: A modular filter system (10) for cleaning of gaseous fluid has at least one housing module (16) with at least one support (18) in which at least one filter element (20) is arranged and at least one duct for the gaseous fluid on the clean side of the at least one filter element (20). At least one housing module (16) has at least one housing frame part (24) which comprises at least one support section (38). The at least one support section (38) is suitable for realizing at least one support (18). The at least one housing frame part (24) has at least one duct section (40). The at least one duct section (40) is suitable for realizing at least one duct or duct part (22). The at least one housing frame part (24) can be applied in the housing module (16) such, that its at least one support section (38) can form at least one support (18) and/or its at least one duct section (40) can form at least one duct.
