Abstract
(EN)
A filtering system that includes a cleaning assembly and a filter element (121) in the form of a plate with a plurality of long, narrow through openings or slits (74, 76, 78, 80) in each of a plurality of rows. The cleaning assembly includes a slit cleaning system (102, 134) connected downstream of the filter element to clean each slit. The cleaning assembly may also include a scraper cleaning system (113, 116) positioned upstream of the filter element. As fluid enters the filtering system, the debris or trash is filtered from the fluid and deposited on the upstream surface of the filter element and in the slits for removal by the cleaning assembly.
