Parker 39R20A String-wound Cartridge Filter 1 Micron

Product Description

The PARKER 39R20A is a string-wound sediment cartridge filter designed for plumbing and water treatment applications requiring fine particulate removal down to 1 micron. Built from FDA-grade cotton wound over a polypropylene plastic core, this cartridge measures 2.5 inches in outside diameter and 20 inches in length. It handles water at temperatures up to 120 degrees F, making it suited for cold and warm water supply lines in residential and light commercial filtration systems. Licensed plumbers and water treatment technicians typically specify this style of cartridge where high dirt-holding capacity and consistent micron performance are required.

This cartridge filter is used in standard filter housings that accept a 2.5-inch OD, 20-inch string-wound element. Typical installations include point-of-entry sediment prefiltration on potable water systems, irrigation supply lines, and process water applications where sand, silt, rust, and other suspended solids must be reduced before water reaches downstream equipment or fixtures. Its 1-micron rating provides fine filtration suited to sensitive downstream components.

Installation Notes

Installation is typically performed by a licensed plumber or water treatment technician. Shut off the water supply and relieve system pressure before opening the filter housing. Inspect the housing o-ring for wear and replace if needed before seating the new cartridge. Observe applicable local plumbing codes and the International Plumbing Code (IPC) for potable water system work.
