{"product_id":"nelsen-24-x-72-filter-unit-1","title":"Nelsen 24 x 72 Filter Unit","description":"\u003cp\u003eThe Nelsen 24 x 72 Filter Unit is a large-capacity commercial backwashing filter designed for facilities with serious water-treatment requirements. Its 24\" x 72\" mineral tank holds a generous media volume, while the Nelsen WS2EE or WS2QC 2\" control valve provides the lead-free brass durability and programmable intelligence expected in commercial and industrial settings.\u003c\/p\u003e\n\u003cp\u003eWith a 125 gpm service flow and 85 gpm backwash, this unit is sized for hotels, apartment complexes, manufacturing lines, agricultural operations, and other high-demand sites. The tank includes commercial distributors and a gravel support bed, and because you choose the filter media, the system can be configured for sediment removal, iron and manganese reduction, carbon filtration for taste and odor, or acid neutralization.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e2\" top-mount commercial control valve with six fully adjustable cycles\u003c\/li\u003e\n\u003cli\u003eSolid-state microprocessor and easy front-panel settings\u003c\/li\u003e\n\u003cli\u003eFront-panel totalizer for time, days to regeneration, volume remaining, flow rate, and total volume used\u003c\/li\u003e\n\u003cli\u003eRegeneration options: meter immediate, meter delayed, time-clock delayed\u003c\/li\u003e\n\u003cli\u003eOptional double backwash for optimum regeneration and media cleaning\u003c\/li\u003e\n\u003cli\u003e12-volt AC adapter plus proven DC drive for safe, easy installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA coin-cell lithium battery provides an 8-hour carryover so programming survives power interruptions, and post-treated water is used during regenerant refill to keep the cycle clean. The adjustable 6-cycle control orchestrates controlled backwash, down-flow brining and slow rinse, an optional second backwash, fast rinse, refill, and down-flow service for precise, efficient operation. Configured weight is roughly 430 lbs, reflecting the substantial tank and media capacity. For operators who want a single, well-supported platform that handles big flows while reporting exactly what it is doing, this Nelsen 24 x 72 unit is a strong, long-lasting commercial choice.\u003c\/p\u003e\n\u003cp\u003eWith a tall 72-inch vessel, this unit provides generous freeboard for the media to expand fully during backwash, which is essential for thorough cleaning and consistent long-term performance. In service, water percolates down through the bed where contaminants are captured; in regeneration, the flow reverses to fluidize and rinse the media, carrying trapped solids to drain. Because the operator chooses the media, the platform adapts to a wide range of water-quality challenges, and it can be re-bedded later if conditions change without swapping the valve or tank. For larger commercial properties, the combination of high media capacity, robust distributors, and the Nelsen valve's totalizer reporting delivers both treatment performance and the operational visibility that keeps maintenance predictable and equipment protected.\u003c\/p\u003e","brand":"Nelsen Corporation","offers":[{"title":"Default Title","offer_id":45668877140021,"sku":"WS20EE-AF24","price":5802.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/4950\/2261\/files\/ws20-ta_d44ec8e1-9752-487a-9dc9-4d8443e29314.jpg?v=1782680074","url":"https:\/\/watersoftenerplus.com\/th-as\/products\/nelsen-24-x-72-filter-unit-1","provider":"Water Softener Plus","version":"1.0","type":"link"}
