It is designed for installation inside 20-inch Big Blue filter housings, including the Stage 2 of UV7510.\u003c\/p\u003e\u003cp\u003eGranular activated carbon is held between a 70-micron porous polyethylene outer shell and a central spun polypropylene core. The nominal dimensions are specified as 20 inches in length by 4.50 inches in outer diameter (114 mm by 508 mm). The assembly includes polypropylene end caps and Buna-N gaskets.\u003c\/p\u003e\u003cp\u003eMinimizing carbon dust release, the radial path allows water entry from the outer shell to the central core. Testing indicates an initial pressure drop of 0.90 psi at a test flow rate of 15.1 Lpm. The cartridge operates on cold water supplies with a limit temperature of 51.7 degrees Celsius.\u003c\/p\u003e\u003cp\u003ePoint-of-entry water lines can employ this cartridge, which is identified by orderable part number RFC20BB. The model RFC20-BB is Tested and Certified by NSF International to NSF\/ANSI Standard 42 for material requirements only. Servicing guidelines recommend replacing the carbon cartridge every 6 to 12 months.\u003c\/p\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eRadial flow carbon design provides chlorine taste reduction with low pressure loss.\u003c\/li\u003e\n\u003cli\u003eTested and certified by NSF International to NSF\/ANSI Standard 42.\u003c\/li\u003e\n\u003cli\u003ePorous 70-micron polyethylene outer shell captures incoming sediment.\u003c\/li\u003e\n\u003cli\u003eCentral spun polypropylene core stops release of carbon fines into plumbing.\u003c\/li\u003e\n\u003cli\u003eNominal 20-micron filtration rating traps fine rust flakes and silt.\u003c\/li\u003e\n\u003cli\u003eFits standard Big Blue 20-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":51091763298551,"sku":"RFC20BB","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/onga-rfc20bb-radial-flow-granular-carbon-20-micron-4-5-x-20-replacement-cartridge.png?v=1788173980","url":"https:\/\/foundationpumps.com.au\/products\/onga-rfc20bb-radial-flow-granular-carbon-20-micron-4-5-x-20-replacement-cartridge","provider":"Foundation Pumps","version":"1.0","type":"link"}
