FIELD: accurate filtering lattices in various branches of engineering. SUBSTANCE: lattice has filter in the form of many layers placed on one another. Each filter of many layers consists of wires triangle or trapezoidal in cross-section installed parallel to one another with continuous slot V-shaped in cross-section. The slot is formed by respective neighboring wires and its width increases inside from lattice surface. Wires of one filter cross the wires of the other filter and respective filters are fastened with each other in points of wire crossing of respective filters. In one version of the claimed lattice, wires are formed with narrow protrusions extending in longitudinal direction of wires to simplify electric welding of filters of neighboring layers. EFFECT: higher efficiency. 3 cl, 8 dwg
