Filter Element for Filtering Fluids

摘要

A filter element for filtering fluids has a support tube having a circumferential wall provided with passages for a fluid. A hollow elongate filter medium is arranged axially on the support tube. The passages are adapted in regard to size; distribution; or size and distribution to a fluidic configuration of the filter element such that non-uniform fluid flows that exist in operation of the filter element upstream of the support tube are compensated. The filter element is used in particular in air filters for internal combustion engines.
