Cryspool Pool Filter Cartridge 27 x 7 Replacement for Jandy CL340/CV340 — Trilobal Fiber, Deep-Pleat High Capacity

Cryspool 07079 is a 27" x 7" replacement pool filter cartridge designed to fit Jandy CL340/CV340-style housings and deliver deeper mechanical filtration with easy cleaning.

This Cryspool cartridge is built as a direct-fit alternative to OEM part numbers such as Jandy CL340, CV340, R0554500 and others, offering a high-filtration surface area and reinforced construction for reliable particle capture. Its trilobal fiber fabric and expanded pleat area increase dirt-loading capacity while remaining user-serviceable: wash and reinstall to extend service life. The cartridge dimensions and top/bottom openings match standard Jandy-style filter housings so installation is straightforward for pool owners and service technicians.

How does this cartridge improve filtration compared to a basic filter?

The Cryspool 07079 uses trilobal polyester fibers and a deep-pleat design to increase the effective filtration surface, which traps more fine particles without a significant pressure rise. The larger surface area helps maintain clearer water between cleanings and reduces strain on your pump when the cartridge is maintained properly.

• Filtration area: 4 × 85 sq.ft. for extended dirt capacity
• Trilobal fiber material captures finer debris than plain point-bond fabric
• Deep pleats minimize pressure increase for longer intervals between cleanings

Will this fit my Jandy CL340 or CV340 filter housing?

Yes — the Cryspool 07079 is sized and ported to replace Jandy CL340/CV340 cartridges and cross-references commonly used part numbers. Confirm your housing accepts a 27" length and 3" openings top and bottom before ordering to ensure a proper seal and fit.

• Length: 27" and outside diameter: 7"
• Top/bottom opening: 3" to match Jandy-style installations
• Compatible references: CL340, CV340, R0554500, PJAN85, C-7459, FC-0800, A0557900

How should I clean and maintain this cartridge to get the longest life?

Clean the Cryspool cartridge when the system pressure reaches the manufacturer’s suggested level or when flow diminishes. The trilobal fabric structure allows dirt to release more easily during rinsing; occasional deep soaking with a cartridge cleaner will remove oils and extend service intervals.

• Rinse with a garden hose from top to bottom between pleats
• Use a commercial cartridge cleaner periodically for oil and mineral buildup
• Inspect end caps and pleats for damage and replace if compromised

What are the construction details and benefits of Cryspool materials?

Cryspool uses an improved trilobal fiber fabric and reinforced end caps to combine strength with high dirt-holding capacity. This construction maintains structural integrity in normal circulation systems and supports repeated cleaning cycles without rapid degradation.

• Trilobal fibers offer higher capacity than typical point-bond fabrics
• Durable pleats and end caps resist collapse under normal operating pressure
• Designed for repeated wash-and-reuse cleaning to lower replacement costs

Who is this for: Pool owners or service professionals using Jandy CL340/CV340-style filter tanks who want a cost-effective, high-capacity replacement cartridge. It’s suitable for residential and light commercial pools where improved particulate capture, straightforward cleaning, and compatibility with Jandy housings are priorities. Always verify dimensions and port sizes against your filter housing before purchase.
