Parker 11R30S Cartridge Filter 50 Micron Cotton 30 in

Product Description

The PARKER 11R30S is a string-wound cartridge filter designed for plumbing and fluid filtration applications. It measures 2.5 inches in outside diameter and 30 inches in length, delivering 50-micron filtration through a cotton wound media wrapped around a stainless steel core. The cotton construction meets FDA material grade standards, making it suitable for applications where food-grade or potable-water compliance is required. This filter is installed by licensed plumbers and water treatment technicians in systems requiring sediment removal at a 50-micron threshold. Its string-wound design provides depth filtration, trapping particles throughout the media rather than just at the surface.

The PARKER 11R30S is used in residential and light commercial water filtration systems, industrial process lines, and point-of-entry water treatment setups. The 30-inch length accommodates high-flow or large-sump filter housings commonly found in commercial plumbing installations. The 50-micron rating makes it appropriate for pre-filtration stages where coarse sediment, sand, rust, and scale particles need to be removed upstream of finer filtration or water treatment equipment. Its FDA-grade cotton media and stainless steel core suit applications where material compatibility with potable water or process fluids is a specification requirement.

Key Features

• 50-micron cotton string-wound media provides effective depth filtration of sediment and particulate
• Stainless steel core adds structural rigidity and resists corrosion under continuous flow
• FDA material grade cotton construction supports potable water and food-process applications
• Rated to 250 degrees F maximum working temperature, suitable for hot-water line service
• 2.5-inch outside diameter fits standard large-sump filter housings
• 30-inch length delivers higher dirt-holding capacity compared to standard 10-inch or 20-inch cartridges

Compatibility

Designed for use in standard 30-inch large-sump cartridge filter housings accepting a 2.5-inch outside diameter element. Verify housing inlet, outlet, and internal diameter specifications before installation.

Installation Notes

This filter is typically installed by licensed plumbers or water treatment technicians. Shut off the water supply and depressurize the filter housing completely before removing or installing a cartridge. Inspect housing O-rings for wear and replace as needed to prevent bypass leakage. Follow applicable local plumbing codes and the housing manufacturer's torque and seating guidelines when reassembling the sump.
