• AXIAL SEAL DESIGN: Securely affixed metal end caps with raised compressed gaskets form a positive axial seal against the air cleaner housing, eliminating air bypass and ensuring 100% of intake air passes through the filter media. Spiral glue binding stabilizes filter pleats under high airflow to prevent bunching and maintain consistent filtration efficiency throughout the service interval — critical in compressor and heavy equipment applications where unfiltered air ingestion causes rapid internal wear.
