The 36\" x 72\" mineral tank is paired with the Nelsen WS2EE or WS2QC 2\" control valve, lead-free brass commercial hardware engineered for heavy, continuous-duty service.\u003c\/p\u003e\n\u003cp\u003eThe system provides a 125 gpm service flow and 85 gpm backwash, making it suitable for large facilities, processing plants, irrigation, and high-occupancy buildings. Commercial distributors and a gravel underbed come standard, and the open media choice means this platform can be set up for sediment filtration, iron and manganese removal, chlorine and taste\/odor reduction with carbon, or pH correction, depending on your water analysis.\u003c\/p\u003e\n\u003ch3\u003eCommercial-grade control\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2\" top-mount valve built for commercial and industrial applications\u003c\/li\u003e\n\u003cli\u003eSolid-state microprocessor with accessible front-panel programming\u003c\/li\u003e\n\u003cli\u003eTotalizer reporting time of day, days to regeneration, volume remaining, flow rate, and total usage\u003c\/li\u003e\n\u003cli\u003eMeter immediate, meter delayed, and time-clock delayed regeneration\u003c\/li\u003e\n\u003cli\u003eOptional double backwash for the deepest media cleaning and efficiency\u003c\/li\u003e\n\u003cli\u003e8-hour lithium battery backup and a reliable DC drive\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe fully adjustable 6-cycle program steps through controlled backwash, down-flow brining and slow rinse, a second backwash when activated, fast rinse, refill, and down-flow service, giving operators granular control over performance. Regenerant refill is drawn from post-treated water, and a 12-volt AC adapter keeps installation safe and straightforward. With a configured weight near 827 lbs, this is a substantial, install-once filtration solution. Facilities that need very high media volume, dependable automation, and full operational visibility will find the Nelsen 36 x 72 a capable workhorse backed by trusted Nelsen control technology.\u003c\/p\u003e\n\u003cp\u003eAt 36 inches in diameter, this is among the larger single-tank commercial filters, and its substantial media volume translates directly into higher contaminant-holding capacity and longer runs between regenerations. Effective backwashing remains essential at this size, which is why the controller and distributor system are engineered to fluidize the full bed and flush captured solids cleanly to drain. The open media selection lets the platform target whatever the water analysis dictates, and the heavy commercial vessel is built to handle the weight and pressure of a deep bed. For high-throughput facilities, pairing this large-capacity tank with the Nelsen valve's adjustable cycles and clear reporting yields a filtration system that performs at scale while remaining transparent and serviceable for the operators responsible for it.\u003c\/p\u003e","brand":"Nelsen Corporation","offers":[{"title":"Default Title","offer_id":45668905287733,"sku":"WS20QC-AF36","price":9237.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/4950\/2261\/files\/ws20-ta_d3178658-8b26-45f9-903e-a92a48ee2c8a.jpg?v=1782680081","url":"https:\/\/watersoftenerplus.com\/es\/products\/nelsen-36-x-72-filter-unit-1","provider":"Water Softener Plus","version":"1.0","type":"link"}
