FIELD: filtration, particularly brush filters.
SUBSTANCE: device comprises body for fibers receiving having inlet end with at least one inlet orifice and outlet end with at least one outlet orifice. The body defines fiber boundary, wherein the fibers extend in parallel between inlet and outlet body ends. Longitudinal gaps are provided between the fibers. The gaps create channels for fluid flow. At least part of the body is made as flexible membrane surrounding fibers. The device also has compression means to apply pressure to outer flexible membrane surface and to compress the fibers in radial direction in at least one section along fiber lengths.
EFFECT: increased filtration efficiency.
