Parker E15R20A String-wound Filter 20 Micron 2.5in Od 20in

Product Description

The PARKER E15R20A is a string-wound cartridge filter designed for plumbing and liquid filtration applications. It features a rayon winding over a polypropylene plastic core, providing 20-micron filtration to remove sediment, dirt, rust, and particulate matter from water lines and process fluid systems. The outer diameter measures 2.5 inches and the filter is 20 inches long, fitting standard sump-style filter housings. Materials meet FDA grade requirements, making it suitable for potable water and food-adjacent applications. Plumbers and water treatment technicians install this cartridge as a point-of-entry or point-of-use pre-filter stage.

This filter is used in residential and light commercial plumbing systems where particulate removal is required upstream of appliances, water heaters, or softeners. The string-wound construction provides graduated depth filtration, capturing larger particles at the outer layers and finer particles closer to the core. The 20-micron rating makes it appropriate for general sediment control in municipal and well water supply lines. Maximum working temperature is 120 degrees F, limiting use to cold and warm water service lines rather than high-temperature process applications.

Installation Notes

A licensed plumber or water treatment technician should install this cartridge following local plumbing code requirements. Shut off the water supply and relieve system pressure before opening the filter housing to swap cartridges. Inspect the housing O-ring for wear and replace if needed before reinstalling the sump bowl. Do not exceed the 120 degrees F rated working temperature or use this cartridge in applications outside its rated micron and material compatibility.
