Abstract
A Vacuum conveyor device () with a multi-stage filter system, has at least one inner filter (A), one outer filter (B), and one filter adapter () especially for air-tight and/or fluid-tight insertion of at least one of the filters, for which the outer filter is arranged up-stream of the inner filter. In order of preparing a filter system for a vacuum conveyor device, which features both the cleaning-related elements of conventional filters and also the safety-related advantages of multi-stage systems, but which remains compact in structure, the one or more inner filters (A) are used as carrier units for the one or more outer filters (B) that can be mounted on or inserted into these inner filters and can be connected or are connected to the filter adapters ().
