Unicel C-7458 Replacement Filter for Hayward CX480XRE | 56 Sq. Ft.

Overview

The Unicel C-7458 is a pleated polyester cartridge filter element engineered for residential and light commercial pool applications, providing 56.0 sq ft of filtration area through a high-density Reemay nonwoven polyester media pack. Dimensional specifications: 7.0-inch OD, 1.875-inch ID, and 19.5625-inch overall length, with ABS injection-molded end caps configured closed-bottom and open-flow top, seated on a Schedule-40 PVC core for axial rigidity. Nominal filtration efficiency falls within the 15–20 micron range under standard test conditions. The element is rated for continuous service to 104°F and operating pressures to 25 PSI, with rated flow capacity of 112 GPM at clean differential. End cap adhesive is UV-stabilized and chemically resistant under standard pool water chemistry, supporting reliable bypass-free seating across the cartridge service life.

Service interval recommendation: residential installations — chemical soak (TSP or enzyme cleaner) every 3–6 months; replacement at ΔP ≥ 8 PSI above clean-filter operating baseline, or on an annual calendar cycle, whichever occurs first. Verify post-installation pressure against documented clean baseline; flag any deviation > 2 PSI for housing or O-ring inspection. Chemical compatibility: continuous service at ≤ 10 ppm free available chlorine; bromine compatible without restriction; muriatic acid soak (1:20 dilution, 20-minute maximum exposure) approved for calcium scale removal, with thorough fresh-water rinse before reinstallation. Enzyme cleaners compatible without restriction. ABS end cap construction permits standard acid wash procedures without bond degradation. Standard Unicel 90-day manufacturer's defect warranty applies through authorized distribution.
