Heavy-Duty Truck Air Filter Outer Mesh with High-Precision Spiral Forming

The heavy-duty truck air filter outer mesh is an essential component of heavy-duty truck air filter systems. It protects pleated filter media, stabilizes airflow, and prevents deformation under high dust loads, vibration, and intake pressure.

With stricter emission standards and increasing engine performance, manufacturers are shifting toward automated production to achieve higher strength, accuracy, and consistency in outer metal mesh structures.

Function of Outer Mesh

Heavy-duty air filters operate in harsh environments, including strong vibration, high dust concentration, powerful airflow, and long operating hours.

The outer mesh provides:

Structural support: Maintains the cylindrical shape of pleated filter media and ensures stable filtration performance.
Durability: Surface-treated metal mesh resists corrosion, abrasion, and temperature variation, extending filter service life.

Manufacturing Trends: Automation vs. Manual Winding

Manual or semi-automatic winding methods often result in inconsistent diameter, uneven pitch, weak seams, and higher defect rates.

Automated spiral rolling technology offers clear advantages:

Accurate control of diameter and spiral pitch
Integrated seam locking and cutting
Higher productivity with consistent quality
Reduced labor cost

Automation has become essential for meeting international OEM requirements for heavy-duty air filters.
