Unicel T-380R Replacement Filter for Harmsco ST | 6 Sq. Ft.

Overview

The Unicel T-380R is a pleated polyester cartridge filter element engineered for Harmsco commercial water filtration applications, providing 6.0 sq ft of filtration area in a compact, high-strength format suitable for industrial and light commercial circulation systems. Media construction is Reemay-grade nonwoven polyester pleated around a perforated rigid core for axial stability under sustained operating pressure. End cap construction is molded polymer with concentric sealing geometry matched to Harmsco ST-series housing seats. The element is rated for continuous service in commercial filtration duty cycles where consistent micron-rated particulate removal and pressure stability are required. Operating pressure capability and high-strength core specification support service in pump-driven circulation loops exceeding typical residential PSI ranges.

Service interval recommendation: commercial installations on 30–90 day rotation depending on bather load, turbidity inlet conditions, and turnover rate; pressure-differential replacement trigger at ΔP ≥ 8–10 PSI above clean operating baseline. Maintain filter replacement log documenting date, technician ID, and part number for compliance with applicable health department reporting requirements. Chemical compatibility: polyester media tolerates continuous service at ≤ 10 ppm free available chlorine; compatible with muriatic acid soak at 1:20 dilution (20-minute maximum exposure) for calcium scale removal; enzyme cleaner compatible without restriction. Rinse thoroughly and verify post-installation pressure against clean baseline before returning system to service. Standard Unicel 90-day manufacturing defect warranty applies through authorized distribution.
