Nelsen AIO 12"x52" Sulfur Filter System

The Nelsen AIO 12" x 52" Sulfur Filter System parcel-delivery edition combines high treatment capacity with the convenience of carrier shipping. This single-tank air injection oxidizing filter removes hydrogen sulfide from well water chemical-free, banishing rotten-egg odor from every tap in larger homes that need the extra capacity a 12-inch tank provides for their water demand.

Oxidation-Based Sulfur Removal

During service, the system holds an air pocket at the top of its 12" x 52" mineral tank. Water passing through this oxygen-rich zone gives up its hydrogen sulfide to oxidation, and the filter media bed then captures the resulting particles. The Fleck 2510SXT control valve runs an automatic daily backwash, sending trapped sulfur to the drain and refreshing the air pocket so treatment continues seamlessly without chemicals or salt to monitor.
