Because the operator selects the media, the same Nelsen tank-and-valve platform can be redeployed if water conditions change over time. For installers, the front-panel programming and totalizer reporting simplify commissioning and ongoing service, while the heavy commercial vessel and lead-free brass valve are chosen for years of dependable, low-fuss operation.

Use the media chart to choose Birm, Centaur, or Katalox-Light® based on your water analysis, then add plumbing connections to complete a chemical-free oxidation filter tuned precisely to your home.\u003c\/p\u003e\u003cp\u003eThe included media selection chart takes the guesswork out of sizing: simply locate your target contaminant and the 16\" tank column to find the recommended cubic footage and resulting service flow. This makes the composite-valve AIO approachable even for installers newer to air-injection systems. With the corrosion-resistant valve body and metered regeneration, the unit is built to deliver years of reliable, low-maintenance service in the damp environments where water-treatment equipment typically lives.\u003c\/p\u003e","brand":"Nelsen Corporation","offers":[{"title":"Default Title","offer_id":45856857227317,"sku":"WSP-IS-AIOCFM15PL","price":3205.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/4950\/2261\/files\/wsp-approved-16x65-primary-8205111590965.jpg?v=1790289528"}],"url":"https:\/\/checkout.watersoftenerplus.com\/collections\/commercial-filtration-systems.oembed","provider":"Water Softener Plus","version":"1.0","type":"link"}
