AI Technical Summary

Benefits of technology

The present invention relates to filters for filtering fluid, including air, liquid, and other fluids. The invention aims to provide filters that have high packaging effectiveness and flexibility in layout, while maintaining performance and maximizing space utilization. The invention includes a plurality of annular filter elements positioned in a housing, which filter fluid by passing it axially through sealed upstream and downstream ends of flow channels. The filter elements can be coiled, corrugated, fluted, radially pleated, or circumferentially pleated, with or without embossment. The filter has a plurality of flow path segments, which include first, second, third, and fourth flow path segments. The fluid flows in a cross-flow manner between the different segments. The invention provides filters that offer improved flexibility and performance in filtering fluid.

Problems solved by technology

Filter arrangements with high packaging effectiveness and flexibility in layout remain a continuing need and challenge, including maintaining performance while maximizing space utilization.
