Pentair 155281-43 Deionization Filter Cartridge 1850 Grains

Product Description

The PENTAIR 155281-43 is a 20-inch deionization specialty filter cartridge designed to reduce Total Dissolved Solids (TDS) and Organics (TOC) from water streams. With a capacity of 1850 grains and a flow rate of 1.25 GPM, this cartridge handles the purification demands found in industrial process lines, commercial water treatment systems, and laboratory water supply applications. It measures 20 inches in height with a 4.5-inch diameter and is rated for water temperatures up to 100 degrees F. Licensed water treatment technicians and facility maintenance professionals are the typical installers of this cartridge type.

This filter cartridge is suited for industrial, commercial, and laboratory environments where high-purity water is required. It is commonly installed in multi-stage filtration housings where deionization follows sediment and carbon prefiltration stages. The specialty deionization media targets ionic contaminants and organic compounds, making it appropriate for applications such as laboratory reagent water preparation, industrial process water, and commercial purification systems that require consistent TDS reduction.

Key Features

• 1850-grain deionization capacity for sustained TDS reduction between replacements
• 1.25 GPM flow rate supports continuous-use purification systems
• Reduces Total Dissolved Solids (TDS) and Organics (TOC)
• Rated for water temperatures up to 100 degrees F
• 20-inch length fits standard 20-inch big blue and compatible filter housings
• 4.5-inch diameter fits appropriately sized housings used in industrial and laboratory installations

Compatibility

Designed as an OEM-style replacement specialty deionization cartridge for standard 20-inch filter housings used in industrial, commercial, and laboratory water treatment applications.

Installation Notes

Installation should be performed by a qualified water treatment technician or licensed plumber familiar with multi-stage filtration systems. Shut off the water supply and relieve system pressure before opening the filter housing to replace the cartridge. Follow applicable plumbing codes, including IPC guidelines, for potable and process water system work. Do not exceed the rated maximum water temperature of 100 degrees F during operation.
