Unicel C-8474 Replacement Filter for Pentair TX-50 (alt) | 75 Sq. Ft.

Overview

The Unicel C-8474 is a pleated polyester cartridge filter element engineered for medium-capacity residential and light commercial applications, providing 75.0 sq ft of filtration area through a high-pleat-count Reemay spunbond polyester media pack. Dimensional specifications: 8.4375-inch OD, 4.0625-inch ID, 14.75-inch length, with closed-top and open-bottom ABS injection-molded end caps seated on a perforated PVC core for axial rigidity under operational load. Nominal filtration efficiency is 20 microns under standard test conditions. The element is rated for continuous service at temperatures up to 104°F and operating pressures to 50 PSI, with UV-stabilized end cap adhesive specified for resistance to standard pool water chemistry. Pleat geometry and core specification deliver consistent flow distribution across the media surface, minimizing channeling under sustained turnover.

Service interval recommendation: residential installations — replacement triggered at ΔP ≥ 8–10 PSI above clean-filter operating baseline, or on an annual calendar cycle, whichever occurs first; commercial installations — 30–90 day service cycle pending bather load and turnover rate, with ΔP log documentation for jurisdictional health code compliance. Rinse with fresh water every 4–6 weeks; chemical soak with TSP or enzyme cleaner every 3–6 months to remove oils, surfactants, and organic loading that resist standard rinsing. Chemical compatibility: continuous service at ≤ 10 ppm free available chlorine; muriatic acid wash compatible at 1:20 dilution (20 minutes maximum exposure) for calcium scale remediation; enzyme cleaners compatible without restriction. Post-installation, verify clean-filter pressure baseline and document for future ΔP reference. Standard Unicel 90-day manufacturing defect warranty applies through authorized distribution channels.
