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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e50-micron cotton string-wound media provides effective depth filtration of sediment and particulate\u003c\/li\u003e\n  \u003cli\u003eStainless steel core adds structural rigidity and resists corrosion under continuous flow\u003c\/li\u003e\n  \u003cli\u003eFDA material grade cotton construction supports potable water and food-process applications\u003c\/li\u003e\n  \u003cli\u003eRated to 250 degrees F maximum working temperature, suitable for hot-water line service\u003c\/li\u003e\n  \u003cli\u003e2.5-inch outside diameter fits standard large-sump filter housings\u003c\/li\u003e\n  \u003cli\u003e30-inch length delivers higher dirt-holding capacity compared to standard 10-inch or 20-inch cartridges\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 30-inch large-sump cartridge filter housings accepting a 2.5-inch outside diameter element.

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.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: String-Wound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMicron Rating\u003c\/strong\u003e: 50 micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 30 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter Media Material\u003c\/strong\u003e: Cotton\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCore Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: FDA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 11R30S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541682585906,"sku":"11R30S","price":49.33,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/714b7c30850e5aa8dd4e4435c4c1bf58_971a39c8-05cd-4fa0-b9d1-75e3ee0281ee.jpg?v=1785882148","url":"https:\/\/voomisupply.com\/products\/parker-11r30s-cartridge-filter-50-micron-cotton-30-in","provider":"Voomi Supply","version":"1.0","type":"link"}
