Unicel 4 NEW T-380 T-380R Harmsco Replacement Swimming Pool Cartridge Filters

The T 380 Red Top was the first filter cartridge sold under the Unicel label. The Red Top cartridge, developed in 1984, was the vanguard of the entire Unicel replacement line introduced one year later at the National Expo in New Orleans. The Unicel T 380 Red Top was also the first filter cartridge to be made using E.I. Dupont's T 380 grade, 4 oz. Reemay. Developed specifically for the Red Top, T 380 media proved to have such excellent filtration efficiency and cartridge dirt holding capacity that virtually every major filter manufacturer serving the swimming pool industry today has adopted this media. Both laboratory tests and field usage have proven that Red Top cartridges are easier to clean and last longer than competitive universal type cartridges. Red Top cartridges easily pass NSF requirements of 70% turbidity reduction in five turnovers, obtaining a 71% reduction in only two turnovers and reaching 98% after five. In addition, the Florida Department of Health and Rehabilitative Services has approved T 380 Red Top cartridges for commercial use. T 380 Red Top cartridges are manufactured with 6 sq. ft. of media and measure 9 3/4" in length and 2 3/4" in diameter. They fit all cluster type filter housings, including Harmsco, American, Pac Fab, Premier, Rainbow, Swimquip, and Swimrite. 1 Buy = 4 Cartridge Filters!
