Abstract

A filtering cartridge (62) with two filter elements (12, 14) having a common axis to filter contaminated fluids such as motor oils or edible oils. The filter elements (12, 14) are composed of a roll of a double-layered, honeycombed, plastic-containing paper. An intermediate space (32) isolated from the outside by a sleeve (10) is formed between the filter elements (12, 14). The filtering cartridge (62) is located in a housing (64). The intermediate space (32) communicates with a fluid presettling section. As shown by the arrows, the fluid is axially pressed through the filter elements (12, 14) and comes out at the front surfaces (56, 58). Thus only filtered fluid is collected inside the housing (64). In addition, the housing (64) is unpressurized.
