FIELD: liquids and solid particles separation. SUBSTANCE: operational capabilities of slit-type filter are expanded due to increase of quality of clearance, increase of durability of filter operation and its capability for self-clearance. Slit-type filter has metal body with holes, central perforated pipe, located in lower part of body tray, supporting disk welded to upper part of central pipe, plates of filtering member mounted between tray and supporting disk, The plates are rigidly fixed on axes, upper part of which is mounted with capability to rotate in central supporting disk and spring-loaded in tangential direction by spring and lower part of the axes is mounted in tray.
