Why this cartridge stands out
- Reinforced center cores provide even stress distribution and higher debris loading, helping prevent cartridge collapse under heavy use and extending time between cleanings.
- Premium filter media uses durable polyester media with sharp pleat folds that prevent bridging, allowing dirt to penetrate deep for efficient filtration and easier cleaning.
- Antimicrobial end caps are reinforced for added strength and treated to repel odor-causing bacteria and mold, offering protection in damp environments. The formulation resists deterioration from salt pools and high chlorine.
- Extruded PVC center cores deliver the strongest construction with round holes that promote even stress distribution, reducing the risk of cracks or collapse.
- Wider break-resistant bands keep pleats evenly spaced, maintain optimal flow, and prevent pleat flutter caused by housing turbulence.
- End caps with integrated fittings simplify installation and removal, eliminating the need for PAD adapters that can impede flow and filtration.
- Embossed part numbers make re-ordering a breeze, so you can maintain peak filtration without guesswork.
