This will reduce the wastewater from your RO unit - which is ideal for saving money if you are on a water meter or wish to produce RO water quicker.\u003c\/p\u003e\n\u003cp\u003eQuick and simple to install!\u003c\/p\u003e\n\u003cp\u003eWe also offer a choice of membrane which is either a 200, 300 or 400 gallon per day membrane.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease Note: it is very important that your system has a flow restrictor suited to the membrane. If you are increasing your membrane GPD then you will likely need to increase your flow restrictor too.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe size of the Flow Restrictor required depends upon the size of the membrane being used.\u003c\/p\u003e\n\u003cp\u003eFlow Restrictors create back-pressure throughout the reverse osmosis membrane element and maintain a ratio of drain water to pure water at around 3 or 4:1. It is recommended that you replace the Flow Restrictor each time you replace your reverse osmosis membrane to keep your system operating at peak efficiency. The number on the flow restrictor indicates the flow rate, in millilitres per minute. The flow restrictor should match your reverse osmosis membrane's production rate.\u003c\/p\u003e\n\u003cp\u003eInline Flow restrictors are easy to install. They are inserted into the 1\/4\" Drain Line Tubing. Simply push your 1\/4\" poly tube firmly into the quick-connect fittings located on both the inlet and outlet ends of the flow restrictor and you are done. Flow restrictors are rated by a flow rate expressed as millilitres\/minute (ml\/min)\u003c\/p\u003e\n\u003cp\u003eThe following table gives a guideline for selecting an inline flow restrictor for your RO membrane.\u003c\/p\u003e\n\u003cp\u003eIn order to pick the correct flow restrictor suited for your membrane capacity please consult the list below\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e300cc ml\/min - for use with 50 - 75 GPD RO membranes.\u003c\/li\u003e\n\u003cli\u003e450cc ml\/min - for use with 75 GPD RO membranes.\u003c\/li\u003e\n\u003cli\u003e500cc ml\/min - for use with 75-100 GPD RO membranes.\u003c\/li\u003e\n\u003cli\u003e600cc ml\/min - for use with 100 - 150 GPD RO membranes.\u003c\/li\u003e\n\u003cli\u003e800cc ml\/min - for use with 150 - 200 GPD RO membranes.\u003c\/li\u003e\n\u003cli\u003e1000cc ml\/min - for use with 200+ GPD RO membranes.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Finerfilters","offers":[{"title":"No Membrane","offer_id":56193530265975,"sku":"FF-RO-MEM-LRG-UPG-0","price":16.99,"currency_code":"GBP","in_stock":true},{"title":"Vontron 200GPD","offer_id":56193530298743,"sku":"FF-RO-MEM-LRG-UPG-2","price":49.99,"currency_code":"GBP","in_stock":true},{"title":"Vontron 300GPD","offer_id":56193530331511,"sku":"FF-RO-MEM-LRG-UPG-3","price":54.99,"currency_code":"GBP","in_stock":true},{"title":"Vontron 400GPD","offer_id":56193530364279,"sku":"FF-RO-MEM-LRG-UPG-4","price":64.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0950\/9873\/2919\/files\/membrane_housing_kit_200gpd_complete_1.jpg?v=1763355320","url":"https:\/\/www.finerfilters.co.uk\/products\/reverse-osmosis-200-400gpd-additional-membrane-upgrade-kit","provider":"Finerfilters","version":"1.0","type":"link"}
