FIELD: mechanics; filtration.

SUBSTANCE: invention relates to wet-type dust collection and may be used in chemical, textile, food, light and other industries. The filter has a vertical case, an inlet and outlet branch pipes, a rotor-type filter element made up of two stainless steel screens, a jet and a pan for slime. The filter spraying zone is limited by a coaxial cylinder shell. The centrifugal jets are made up of cases with inlets, covers, sealing gaskets, springs arranged between the covers and swirlers. The swirler is a cylinder cup with its bottom turned upward, installed with a circular gap relative to the case.
