It is designed for installation inside 10-inch Big Blue filter housings, including the Stage 2 of UV5505, providing a secondary barrier.\u003c\/p\u003e\u003cp\u003eSurrounding a central water flow core, the carbon block wall is manufactured with specialized lead-reducing binders and polypropylene end caps. The physical dimensions are a nominal 10 by 4.5 inches. The solid structure withstands water pressures up to 500 kPa.\u003c\/p\u003e\u003cp\u003eCyst reduction is achieved mechanically by a nominal 0.5-micron filtration rating, certified to NSF\/ANSI Standard 53 to reduce microscopic cysts such as cryptosporidium and giardia. The cartridge operates on cold water lines with a working temperature range up to 51.7°C, performing chemical reduction.\u003c\/p\u003e\u003cp\u003eInstalling this element requires correct vertical alignment within the filter housing sump to prevent fluid bypass. Cataloged under orderable part number PB3510, it features a high chemical adsorption capacity. To maintain certification compliance, the cartridge requires replacement every 6 to 12 months.\u003c\/p\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eExtruded carbon block structure provides lead adsorption and chemical filtration.\u003c\/li\u003e\n\u003cli\u003eTested and certified by NSF International to NSF\/ANSI Standard 53.\u003c\/li\u003e\n\u003cli\u003ePolypropylene end caps provide stable sealing inside 10-inch sumps.\u003c\/li\u003e\n\u003cli\u003eNominal 0.5-micron filtration rating captures giardia and cryptosporidium cysts.\u003c\/li\u003e\n\u003cli\u003eResists chemical degradation and provides high chlorine odor reduction.\u003c\/li\u003e\n\u003cli\u003eFits standard Big Blue 10-inch filter housings for point-of-entry loops.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWarranty: Pentair warrants this product against defects in materials and workmanship under normal use and service for a period of one year from the invoice date.\u003c\/p\u003e","brand":"Onga","offers":[{"title":"Default Title","offer_id":51091763200247,"sku":"PB3510","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/onga-pb3510-extruded-carbon-block-lead-cyst-0-5-micron-4-5-x-10-replacement-cartridge.png?v=1788173974","url":"https:\/\/foundationpumps.com.au\/products\/onga-pb3510-extruded-carbon-block-lead-cyst-0-5-micron-4-5-x-10-replacement-cartridge","provider":"Foundation Pumps","version":"1.0","type":"link"}
