Nelsen 5600 AIO 12X52 Sulfur System

When sulfur odor demands a higher-capacity solution, the Nelsen 5600 AIO 12X52 Sulfur System provides the tank volume and media depth needed to handle it. This 12" x 52" air injection unit drives out hydrogen sulfide and its signature rotten-egg smell across the whole house, all without salt or chemical additives, making it ideal for busy households where odor-free water matters at every tap.

Air Injection in Action

The Fleck 5600SXT control valve maintains an air pocket inside the mineral tank. As water passes through this oxidizing zone, dissolved sulfur converts to a filterable form that the media bed captures and holds. On a programmed schedule, the valve backwashes the bed, sending trapped contaminants to drain and refreshing the air cushion automatically, so the system keeps performing without any chemical replenishment between cycles.

The wider 12-inch tank boosts service flow, making this model a strong match for larger families or wells with stubborn hydrogen sulfide and heavy simultaneous demand. As a point-of-entry system, it ensures every shower, tap, and appliance receives odor-free water from a single installation. Built around the proven Nelsen AIO platform and supplied complete by Water Softener Plus, it combines dependable 5600SXT automation with generous media capacity for consistent, low-maintenance performance over the long haul.

When planning the install, locate the system at the point of entry ahead of any softener so hydrogen sulfide is removed before it reaches other equipment or the water heater. A nearby drain handles backwash discharge, and the control head plugs into a standard outlet. Because sulfur problems can fluctuate seasonally on some wells, the scheduled backwash keeps odor control steady even as conditions change throughout the year.

Supplied and supported by Water Softener Plus, this Nelsen-built system reflects the quality and consistency homeowners and installers have come to expect from the brand, giving you confidence in a long, dependable service life treating your home's water.
