How it works
The valve draws a pocket of air into the top of the tank. Water passes through the air, which oxidizes iron, manganese and hydrogen sulfide into particles, and the media bed filters them out. Every day the valve backwashes the bed, sends the trapped particles to drain and refreshes the air pocket.
Media benefits
- Removes dissolved iron: clear water with no orange or brown stains
- Protects fixtures, laundry, water heaters and appliances
- Daily automatic backwash sends the trapped iron to drain
- Air injection oxidizes iron, manganese and sulfur with plain air, so no chemicals or chlorine are added

The NWS Control Flow AIO 12"x52" Iron System scales up ' metered iron filtration for larger homes and heavier iron loads. Its 12" x 52" polyglass tank holds 1-3/4 cubic feet of iron-reduction media, delivering ample capacity and service flow for demanding households with multiple bathrooms or high daily water use.
Air injection oxidation drives the treatment: a maintained air pocket converts dissolved iron into filterable particles that the media bed captures. Control Flow Technology meters regeneration to actual water consumption, backwashing only when needed to flush iron and renew the air cushion — all without salt, chlorine, or potassium permanganate. The result is dependable iron control with no chemicals to buy or store.

Built for Bigger Demand
The wider 12-inch tank increases both treatment capacity and service flow rate, making this system well suited to larger families or wells with significant iron staining. Installed at the point of entry, it keeps plumbing, water heaters, fixtures, and laundry free of the rust-colored buildup that untreated iron causes. The optional tank jacket gives the unit a cleaner look in finished spaces. Supplied by Water Softener Plus, it arrives nearly complete — add the adapters that match your connections — for efficient, salt-free, low-maintenance iron control across the whole home.
Routine ownership is refreshingly simple: with no salt or chemicals involved, there are no consumables to restock between regenerations. Over many years the media will eventually exhaust and can be replaced to restore full capacity, but the tank, valve, and bypass continue to serve. Confirming your incoming pH and iron level at setup helps ensure the oxidation process works as intended and that you get clear, stain-free water from day one.
As part of the Water Softener Plus catalog of well-water treatment equipment, this unit is chosen and assembled to deliver consistent, real-world results, helping you protect your plumbing investment while enjoying noticeably better water at every fixture in the house.
