Description

The Pleatco Ultra-A3-PAK4 is engineered for longevity and performance. It replaces multiple OEM cartridges—Hayward CX570XRE, CX480XRE, PA75SV-PAK4, and PA81-PAK4—simplifying stock. PurePleat technology preserves pleat structure, while Point-Bonded fabric ensures even filtration. The Free-Flow Core lowers pump stress and extends filter cycles.

Pro Tip

Rinse monthly using low-pressure water to maintain pleat integrity. Ensure proper o-ring and manifold fit when replacing OEM cartridges.

Installation Tips

Match cartridge to OEM dimensions for proper fit. Use only low-pressure rinsing to clean—high-pressure can damage filter media.
