About This Item

The Unicel C-7652 is a 7000 Series replacement filter cartridge engineered to match the fit and form of cartridges used in Sta-Rite Posi-Clean pool filter systems. Built with heavy-duty 4 oz. Reemay 2040 spun-bonded polyester media and 110 precision pleats across a 50 sq. ft. filtration area, this cartridge delivers the filtration performance your Posi-Clean system was designed for.

⚠️ IMPORTANT: SINGLE CARTRIDGE — SOME SYSTEMS REQUIRE TWO
This listing is for one (1) C-7652 cartridge. The Sta-Rite Posi-Clean FCP100 and TXC100 systems require two (2) cartridges to complete a full 100 sq. ft. filtration element (combined OAL: 38 3/4"). Single-element systems (FCP50, FCP50B, TXC50, TXC50B) require one cartridge. See compatibility table below for your model.

(This is not an exhaustive list.)

Note from Unicel: The 100 sq. ft. Swimquip system is comprised of two C-7652 cartridges (combined overall length: 38 3/4"). If your filter housing is labeled Swimquip, it may have been manufactured before Sta-Rite's acquisition of the Swimquip product line — confirm your OEM part number against the table above before ordering.

Pro Tip

Before ordering, measure your existing cartridge: length (end cap to end cap), outer diameter, and inner diameter. The C-7652 measures 19 3/8" long × 7" OD × 3" ID. Cross-reference your filter's OEM part number — 24241-0016 or WC108-141SI — against the compatibility table above to confirm this is the correct cartridge for your system. If your system holds two cartridges, order a quantity of two.

About Unicel Filter Cartridges and DE Grids

The "Gold Standard" of Replacement Cartridges
For over 50 years, Unicel (Meissner Mfg.) has been the professional's choice for restoring pool water clarity. While generic "knock-off" filters often use cheap, fuzzy fabric that clogs quickly, Unicel uses genuine Reemay® Filtration Media. This patented synthetic fiber features a unique trilobal shape that traps significantly more dirt and oils without choking your pump's water flow. Based in California, Unicel doesn't just copy filter dimensions; they engineer them to strict Original Equipment Manufacturer (OEM) specifications. This ensures a "lock-tight" fit in your filter tank, preventing debris from bypassing the system and returning to your pool.

Why We Trust Unicel Filter Cartridges and DE Grids
Genuine Reemay® Media: Uses continuous trilobal fibers to capture microscopic debris without restricting water flow.

Precision "Exact Fit": Engineered to match your tank's original specifications for a 100% leak-free seal.

Made in the USA: Manufactured in California with heavy-duty urethane end caps that resist cracking under pressure.

Longer Lifespan: Sharp, rigid pleats resist collapsing during cleaning, meaning you buy fewer replacements over time.
