Pentair 25022-0224S Large Outer Cartridge – 264 sq ft

Part Number: 25022-0224S

Description

This is the large outer cartridge module for the Sta-Rite® System 3 S7M400 modular media filter. It provides 264 sq ft of filtration surface and is engineered to restore optimal flow and service life when the original cartridge has reached its functional limit.

Compatibility & Fitment

  • Designed for use with the Sta-Rite System 3 S7M400 filter tank (21″ diameter modular media filter).
  • Intended to replace the outer cartridge module in a dual-cartridge configuration (inner + outer) in that filter tank.
  • Used when the outer media is clogged, no longer rinses clean, or when permanent loading has reduced flow and cleaning no longer restores performance.

Features & Specifications

  • Filtration area: 264 sq ft — high surface area for extended run times before cleaning.
  • Media construction: reinforced pleated polyester media designed for durability and long service life in pool or spa environments.
  • Dimensions designed for the System 3 S7M400 outer cartridge position.
  • OEM replacement — ensures correct fit, alignment, and hydraulic performance.

Installation Notes

Before installation, shut off pump and relieve system pressure. Open the filter tank, remove the old cartridge module, inspect tank internals and manifold for damage or debris. Insert the new 25022-0224S outer cartridge, reassemble the tank per manufacturer instructions, and restore circulation. Monitor pressure and flow to verify restoration of performance.

Maintenance Tip

Clean the cartridge periodically (as per filter manual) and replace it when cleaning no longer restores acceptable pressure drop, or if flow decreases significantly. Using this high-capacity outer cartridge helps extend service intervals, maintain lower energy draw, and preserve water clarity.
