Abstract: An outdoor air purifier includes a housing including at least one housing cover part, a mounting base, at least one flow inlet for outdoor air to be purified, at least one flow outlet for cleaned air, and an inner clean air space, a fan having a standing rotational axis and arranged within the housing, wherein the at least one flow inlet is arranged radially with regards to the standing rotational axis, and the at least one flow outlet is arranged axially with regards to the standing rotational axis, and at least one filter element at least partially surrounding the inner clean air space. The fan is displaced axially from the mounting base and is in fluid connection with the inner clean air space. The at least one filter element extends essentially parallel to the standing rotational axis.

Abstract: A separator for separating liquid from a gas flow is provided with a nozzle carrier element provided with a nozzle arrangement having one or more nozzles. An impact element is arranged downstream in flow direction of the gas flow at least partially opposite the nozzle arrangement. A permanent cover device is provided that covers at least one of the one or more nozzles of the nozzle arrangement. The permanent cover device reduces by at least 50% a through-flow of the gas flow through the at least one of the one or more nozzles of the nozzle arrangement compared to the one or more nozzles of the nozzle arrangement that are free from the permanent cover device. An assembly kit for producing such a separator is provided with a nozzle carrier element with nozzle arrangement and one or more nozzles, an impact element, a cover device, and a liquid reservoir.

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.
