Pleated filter elements (also known as pleated filters or corrugated filters) are high-performance metal filter elements mechanically pleated from metal filtration materials to significantly increase filtration area, reduce pressure drop, and extend service life. Pleated metal mesh filters allow for larger filtration areas and high fouling control capabilities, and can also fit into smaller housings, which allow for fine filtration without applying significant pressure.

This filter element is available in single- or multi-layer structures and can be combined with sintered mesh, sintered felt, or woven wire mesh media. The pleated design maximizes filtration area in a compact form, making it ideal for high-flow industrial systems requiring low pressure drop and reusable performance.
