FIELD: apparatus for obtaining oil.
SUBSTANCE: invention relates to oil production and can be used together with oil well pump unit. Proposed device comprises casing and filtration element arranged concentrically and mechanical impurities accumulator secured to said casing. Filtration element is arranged inside said casing and has inlet holes. Housing is provided with tangential inlet holes and is equipped with a protective shield located above tangential inlet holes, the diameter of which exceeds the diameter of inlet holes of the filter.
EFFECT: efficiency of filtration of gas-liquid mixtures containing mechanical impurities is increased, and the reliability of the filter is increased.
