- Strong, center-core construction: Extruded PVC center cores with round holes provide even stress distribution, helping prevent cracks and collapse under heavy debris loading for longer service intervals.

- Wider, break-resistant bands: Reinforced bands keep pleats evenly spaced, reducing flutter and turbulence inside the housing to maintain steady, high-quality filtration.
