Unicel C-4605 Replacement Filter for Muskin FP-A2027 | 8 Sq. Ft.

Overview

The Unicel C-4605 is a pleated polyester cartridge filter element rated at 8.0 sq ft of effective filtration area, engineered for above-ground and compact in-ground pool filter housings in the Muskin FP-A2027 product family. Media construction utilizes Reemay-style nonwoven polyester fabric at a nominal 20-micron filtration efficiency, supported on a rigid central core with injection-molded ABS end caps for dimensional stability and bypass-free seating. End cap geometry is matched to the FP-A2027 housing seat tolerance, with OD/ID specifications held within ±0.030 inch of OEM dimensional standards. Maximum rated continuous service temperature is 104°F; operating pressure range conforms to standard residential above-ground circulation system parameters (typical 8–20 PSI). The 8.0 sq ft media pack is sized for low-to-moderate turnover applications consistent with the FP-A2027 housing's rated flow envelope.

Service interval recommendation: rinse with fresh water at every 4–6 weeks of operation or upon ΔP rise of ≥ 8 PSI above clean-filter operating baseline, whichever occurs first. Chemical soak in dilute TSP or commercial enzyme cleaner is recommended every 3–6 months to remove oils and surfactant residue not addressed by hose rinsing. Full element replacement is recommended annually, or earlier upon visual evidence of pleat collapse, fabric tearing, or end cap separation. Chemical compatibility: continuous service at ≤ 10 ppm free available chlorine; muriatic acid wash compatible at 1:20 dilution (20-minute maximum soak) for calcium scale removal; enzyme cleaners compatible without restriction. ABS end cap construction tolerates standard acid wash procedures without adhesive degradation. Standard Unicel 90-day manufacturer's defect warranty applies through authorized distribution.
