Unicel C-8411 Replacement Filter for Hayward CX760RE | 75 Sq. Ft.

Overview

The Unicel C-8411 is a pleated polyester cartridge filter element engineered for residential and light commercial pool applications, delivering 75 sq ft of filtration area through a Reemay nonwoven polyester media pack with nominal 20-micron filtration efficiency. Dimensional specifications conform to the Hayward CX760RE form factor: 8-15/16-inch OD, 4-inch ID, 17-3/8-inch overall length, with closed-bottom and open-top ABS injection-molded end caps bonded to the media pack via UV-stabilized adhesive. The element is constructed on a Schedule-40 PVC core for axial rigidity under operating loads, rated for continuous service at temperatures up to 104°F and operating pressures to 25 PSI. End cap geometry is held to ±0.030 inch OD tolerance for confirmed bypass-free seating across compatible filter housings.

Service interval recommendation: residential installations — chemical rinse every 4–6 weeks or at ΔP ≥ 8 PSI above clean-filter baseline; chemical soak (dilute TSP or enzyme cleaner) every 3–6 months to address oils and organic loading that resist mechanical rinsing; annual replacement, or earlier upon visual identification of pleat channeling, fabric delamination, or end cap separation. Chemical compatibility: polyester media supports continuous service at ≤ 10 ppm free available chlorine and is compatible with muriatic acid wash at 1:20 dilution (20-minute maximum exposure) for calcium scale remediation; thorough freshwater rinse required before reinstallation. Enzyme cleaners compatible without restriction. Post-installation pressure verification recommended to confirm clean operating baseline for subsequent ΔP service triggering. Standard Unicel 90-day manufacturing defect warranty applies through authorized distribution.
