Komposit filtermedium

摘要

A composite filter media structure (10) is provided. In an exemplary embodiment, the composite filter media structure includes a corrugated base substrate (12) that includes a nonwoven synthetic fabric formed by a dry-laid process that corrugates the base substrate during the forming process. The composite filter media structure also includes a nanofiber membrane (20) deposited on at least one side of the base substrate by an electro-blown spinning process.
