FIELD: separation.

SUBSTANCE: invention is intended for filtration of fluid medium. Filtering unit for filtration system (10) with reservoir, which is configured to connect to base (12), comprises bushing (36) defining inner space (40) and bushing axis, filtering working medium (34), surrounding bushing, and first end plug (32) attached to bushing and including ring-shaped sidewall (48), oriented substantially perpendicular to first element (46) and covering part of filtering working body, outer wall (54) located at a distance from the first element and enclosing it, several arms extending from the side wall to the outer wall, wherein arms, sidewall, as well as outer wall define holes in first end plug. Assembly includes first sealing element (42) surrounding perimeter of first end plug and including first, second and third sealing surfaces, wherein first sealing surface is configured to receive first radial sealing surface of base, when base is joined to base, second sealing surface is configured to receive sealing surface of reservoir, and third sealing surface is configured to receive axial sealing surface of base; and second sealing element (44) located on the top surface of the end plug and substantially extending above the plane containing the first sealing element. Each arm includes a rib-shaped section having first and second bottom surfaces which together form a first angle of less than about 270°. Several arms are uniformly spaced around the side wall.

EFFECT: technical result is providing high quality of cleaning medium.
