The Onga Clean \u0026amp; Clear Plus 420 addresses this through a large four-cartridge filtration assembly designed to capture fine suspended particles while reducing the frequency of cartridge cleaning.\u003c\/p\u003e\n\n\u003cp\u003eInside the vessel, the combined cartridge surface area reaches 420 sq.ft. \/ 39.0 m² and supports maximum circulation flow rates up to 568 L\/Min. The filter is also rated for approximately 272,550 litres of turnover capacity over an 8-hour operating cycle. Its quad cartridge arrangement provides substantially more available filtration surface area compared with smaller cartridge filter designs, assisting both debris retention and lower hydraulic resistance.\u003c\/p\u003e\n\n\u003cp\u003eThe filter tank is manufactured using injection moulded glass reinforced polypropylene for structural rigidity and corrosion resistance around chemically treated pool water environments. Continuous High Flow™ internal air relief technology assists removal of trapped air from the vessel during operation to support more consistent filtration efficiency and circulation stability.\u003c\/p\u003e\n\n\u003cp\u003eMaintenance access is handled through Pentair’s Tension Control™ clamp system which allows quick separation of the vessel for cartridge rinsing and inspection. A 1\/4 turn air relief valve with integrated hose port assists controlled pressure release before servicing, while the 40 mm drain clean-out port simplifies draining procedures. The unit is supplied with 50 mm barrel unions and requires 1727 mm of vertical clearance for cartridge removal access. :contentReference[oaicite:1]{index=1}\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e420 sq.ft. \/ 39.0 m² effective filtration area for larger residential pool systems\u003c\/li\u003e\n\u003cli\u003eQuad cartridge design assisting longer filtration cycles between cleanings\u003c\/li\u003e\n\u003cli\u003eMaximum operating flow rate reaching 568 L\/Min\u003c\/li\u003e\n\u003cli\u003eApproximate turnover capacity of 272,550 litres over 8 hours\u003c\/li\u003e\n\u003cli\u003eInjection moulded glass reinforced polypropylene vessel construction\u003c\/li\u003e\n\u003cli\u003eBalanced hydraulic flow path supporting efficient cartridge circulation\u003c\/li\u003e\n\u003cli\u003eContinuous High Flow™ air relief system reducing internal air build-up\u003c\/li\u003e\n\u003cli\u003eTension Control™ clamp arrangement simplifying maintenance procedures\u003c\/li\u003e\n\u003cli\u003e1\/4 turn air relief valve with hose port and 40 mm drain clean-out port\u003c\/li\u003e\n\u003cli\u003e10 year pro-rata limited warranty*\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Onga","offers":[{"title":"Default Title","offer_id":50788950606071,"sku":"160301","price":1466.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/onga-cleanclear-plus-420-cartridge-filter-for-high-flow-pool-systems-with-continuous-high-flow-air-relief.png?v=1779099081","url":"https:\/\/foundationpumps.com.au\/products\/onga-clean-clear-plus-420-cartridge-filter-for-high-flow-pool-systems-with-continuous-high-flow-air-relief","provider":"Foundation Pumps","version":"1.0","type":"link"}
