1 Pleating strengthens filter media and increases the filter-element filtration area Pleat heights are a critical part of filter-element design. WIX Filters' special arch-pleat design evenly distributes airflow over more of the filter surface, while preventing pleat collapse that restricts airflow. This design feature is important because it improves filteration at high airflow rates and extends filter effeciency throughout its entire service life.
WIX Heavy Duty air filters come with corrugated filter media made with non-phenolic, resin-impregnated paper, which resists moisture and holds large amounts of dirt to extend service intervals.
2 Specially plated, corrosion-resistant metal end caps are plastisol bonded to the filter media and expanded or perforated metal to create a strong filter body that maintains its shape. The end caps on WIX Heavy Duty air filters:
- Come with welded handles for easy removal and installation on applicable applications.
- Are designed to ensure exacting torque-load distribution on the gasket seals.
- Are engineered with matching inner and outer skirt heights for structural integrity.
3 WIX Filters' rubber-backed sealing washer ensures thread seal distribution of torque on the wing nut. This washer's design matches the geometry of the metal around the bolt-hole area of the end cap.
It must be used, when provided, to properly install the filter and maintain warranty coverage.
Leaking gaskets allow intake air to bypass the filter element altogether, Certain applications call for gaskets of a different material. WIX Heavy Duty air filter gaskets:
- Are impervious to enviromental conditions.
- Do not take a comperssion set.
- Seal by deflection, not distortion.
4 Silicone gaskets are permanently bonded to the end cap, eliminating any possibility of bypass, and stay sealed under all temperatures and vibrations.
WIX Heavy Duty air filters with foam gaskets are applied with a concentric mold and two-part epoxy to insure they are bonded to the end cap, eliminating any possibility of bypass.

5 WIX's Design provides excellent column strength and damage resistance. Column strength is critical in maintaining a flat end cap, which ensures parallel end caps that load the filter gaskets evenly when installed in the aur filter housing.
WIX's inner and outer material is corrosion resistant. The expanded, .028-inch-thick metal mesh:
- Support the media pleats to protect them from impact damage.
- Adds rigidity to the element.
WIX's expanded metal mesh is cold rolled after die cutting and expansion, which leaves a flat smooth surface on both sides, This technique means no sharp edges will cut or tear the filters' pleated media.
