NWTS Control Flow AIO Metered Kit

Upgrading an air injection oxidizing filter to metered operation is one of the smartest efficiency moves an installer can make, and the NWTS Control Flow AIO Metered Conversion Kit makes that upgrade clean and complete. Designed for Nelsen Water Solutions air injection systems, this kit converts a basic AIO valve to demand-initiated, metered control so the filter regenerates based on actual water usage rather than a fixed clock alone.

Everything Needed for the Conversion

The kit arrives with the core components that make metered AIO control possible. Inside you will find a Control Flow board, a Control Flow piston matched to the valve, a flow meter to track volume through the system, and a service manual to guide the swap. Together these parts give the valve the ability to measure throughput and trigger an air-draw and backwash cycle only when needed, which conserves water and keeps the oxidation pocket fresh for iron, manganese, and hydrogen sulfide reduction.

• Converts a Nelsen AIO valve to metered, demand-based operation
• Includes Control Flow (CF) board for metered logic
• Includes CF piston matched to the air injection valve
• Flow meter measures actual water usage for accurate cycling
• Service manual included to guide installation and setup
• Alternate part reference NWTS10CFM-AIO-KIT for identification

Air injection oxidizing filters work by drawing a pocket of air into the top of the media tank, where dissolved iron and sulfur are oxidized as water passes through and then trapped on the filter bed before being flushed during regeneration. Switching from time-only to metered control means the system replenishes that air pocket and cleans the bed in step with how much water the household actually uses, reducing wasted backwash water on light-use days while ensuring capacity on heavy-use days.

This kit is intended for technicians and experienced DIY owners servicing a compatible NWTS air injection system. Before beginning, confirm the kit matches your valve, depressurize and bypass the unit, and follow the included manual for piston and board replacement and meter programming. Done correctly, the conversion delivers smarter regeneration, better media performance, and lower long-term operating cost, turning a capable iron and sulfur filter into a more responsive, water-wise appliance that adapts automatically to real household demand throughout the year for cleaner water.
