Poly-Fine® XLD Filter Cartridges, XLD4520UEM7

The XLD4520UEM7 balances coarse to fine prefiltration at 4.5 µm with a pleated depth design that increases surface area for long service life. Gel-guard media helps capture deformable gels and larger fines that can foul downstream stages. All polypropylene construction avoids surfactants, binders, and adhesives to support clean processing. The single open end (SOE) fin end uses external 226 O-rings in EPDM for quick installation and dependable sealing in compatible housings. With low initial pressure drop and a predictable rise with solids load, this 20-inch element is well-suited for beverage polishing, membrane protection, and plant water cleanup where consistent performance is required.
