Constructed from polypropylene, this bag filter measures 3-7\/16 inches in diameter and 18.5 inches in length, providing 1.75 square feet of filtration area. The semi-rigid body holds its shape under flow, reducing filter collapse and maintaining consistent flow performance throughout its service life. It is installed by plumbing professionals and industrial maintenance technicians in standard Size 5 bag filter housings.\u003c\/p\u003e\n\u003cp\u003eThis filter is suited for residential and light commercial liquid filtration systems where particulate removal at the 10-micron level is required. Typical applications include water treatment systems, process fluid lines, and cooling water circuits that demand reliable particulate capture without frequent changeout. The polypropylene construction offers broad chemical compatibility, making it appropriate for a range of water-based and mildly aggressive fluid systems. Sold individually, it fits directly into standard Size 5 bag filter vessels.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e10-micron filtration rating for effective particulate removal from liquid streams\u003c\/li\u003e\n  \u003cli\u003eSemi-rigid polypropylene construction resists collapse under normal operating flow conditions\u003c\/li\u003e\n  \u003cli\u003eSize 5 bag format fits standard Size 5 filter housing vessels\u003c\/li\u003e\n  \u003cli\u003e1.75 square feet of filter area for extended service intervals between changeouts\u003c\/li\u003e\n  \u003cli\u003e3-7\/16 inch diameter and 18.5 inch length for accurate housing fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for standard Size 5 bag filter housings that accept semi-rigid polypropylene bag elements with a 10-micron rating.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified plumbing or industrial maintenance technician.
