FIELD: filtering gases and liquids.
SUBSTANCE: proposed filter element includes tubular framework with perforations in form of longitudinal slots with filtering partition located on its surface and formed by spirally wound thread; thread is tightened tightly, without gaps due to roughness of thread; width of slots and diameter of thread are dictated required gap between turns at deformation of thread caused by introduction of medium to be filtered. Width of slots and diameter of thread are so selected that their ratio is within 10 and 1000. Roughness of thread is not below 7th class when thread is taut; tension and breaking force are so selected that their ratio exceeds 0.05. Framework may be made in form of "squirrel cage".
EFFECT: enhanced retentivity at low hydraulic resistance; possibility of self-cleaning in the course of operation.
