FIELD: process engineering.
SUBSTANCE: invention relates to filtration. Filter module (10) comprises case (12) with fluid inlet and outlet. Note here that case (12) envelops tubular long filter element (14) and cleaning head (18) connected via revolving coaxially arranged pipe (16). Cleaning head is elastically shifted towards tubular long filter element inner surface. Cleaning head has the adjustable-size hole facing the filter element inner surface to allow communication between case inner part and pipe (16) inner part. Module incorporates the means to create pressure difference between case (12) inner part and pipe (16) inner part to allow fluid to flow from case (12) inner part to pipe (16) inner part.
EFFECT: longer life, decreased servicing intervals.
