FILTER WITH INCREASED FILTRATION AREA Russian patent published in 2017 - IPC B07B1/46 B07B1/49 B01D39/00 

FIELD: technological processes.

SUBSTANCE: for the manufacture of filter, filter frame is casted from composite material. The frame is attached to a plurality of support elements protruding above the filter frame. The first of support elements plurality has a height varying from the first height value above the filter frame to the second height value above the filter frame. Plurality of support elements protrudes above the main part at different heights to form a wavy configuration. Plurality of protrusions protrudes over the main portion and intersects with at least one support element of the plurality of support elements. Fabric net is fused to support elements plurality, whereby the fabric net corresponds wavy profile formed by the plurality of support elements, so that the filter corresponds to a wavy configuration. At least a part of the plurality of support elements and of the plurality of protrusions pass through the net.

EFFECT: increasing the throughput of filters and ease of installation, reducing filtering time.
