The Onga FreeFlo FFSF-28-50 increases vessel size, media capacity, and hydraulic handling capability to better support larger domestic pool systems requiring stronger water circulation and dependable long-duration filtration performance.\u003c\/p\u003e\n\n\u003cp\u003eThe filter provides an effective filtration area of 0.39 m² with maximum operating flow rates reaching 340 L\/Min under normal filtration conditions. During servicing cycles, a minimum backwash flow rate of 230 L\/Min is required to properly agitate and clean the media bed before returning the vessel to standard operation. Media compatibility includes 210 kg of sand or a dual-grade glass media configuration consisting of 120 kg fine glass together with 60 kg coarse glass media depending on installation preference and filtration setup requirements.\u003c\/p\u003e\n\n\u003cp\u003eIts UV resistant fibreglass tank construction is intended for durability within exposed outdoor pool equipment areas and chemically treated residential water environments. The supplied six-function multi-port valve supports multiple operating positions including filtration, rinsing, recirculation, waste, closed, and backwash functions to simplify ongoing maintenance operation. A thermoplastic locking clamp secures the valve assembly while permitting full 360-degree rotational positioning during installation to assist plumbing alignment. Included barrel unions further simplify pipe connection and future servicing access around the filtration system.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e28-inch fibreglass sand filter developed for larger residential circulation systems\u003c\/li\u003e\n\u003cli\u003e50 mm \/ 2\" six-function multi-port valve supplied with the filtration assembly\u003c\/li\u003e\n\u003cli\u003eEffective filtration area of 0.39 m² supporting higher residential turnover demand\u003c\/li\u003e\n\u003cli\u003eMaximum operating flow performance reaching 340 L\/Min during filtration cycles\u003c\/li\u003e\n\u003cli\u003eMinimum required backwash flow of 230 L\/Min for proper media cleaning operation\u003c\/li\u003e\n\u003cli\u003eCompatible with 210 kg sand loading or layered glass media configurations\u003c\/li\u003e\n\u003cli\u003eGlass media setup supports 120 kg fine glass and 60 kg coarse glass media\u003c\/li\u003e\n\u003cli\u003eUV resistant fibreglass vessel construction suited to outdoor pool installations\u003c\/li\u003e\n\u003cli\u003eThermoplastic clamp allowing 360-degree valve rotation during plumbing setup\u003c\/li\u003e\n\u003cli\u003e5 year pro-rata warranty*\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Onga","offers":[{"title":"Default Title","offer_id":50788951982327,"sku":"FFSF-28-50","price":920.68,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/onga-freeflo-28-fibreglass-sand-filter-for-large-pool-systems-with-rotating-thermoplastic-clamp.png?v=1779099706","url":"https:\/\/foundationpumps.com.au\/products\/onga-freeflo-28-fibreglass-sand-filter-for-large-pool-systems-with-rotating-thermoplastic-clamp","provider":"Foundation Pumps","version":"1.0","type":"link"}
