24" X 72" NWS 1.5" Composite Control AIO

The 24" X 72" NWS 1.5" Composite Control AIO is the top-tier air-injection filter in the Nelsen Water Solutions composite-valve series, designed for the highest residential and light commercial demand. The patented air-injection process slowly bleeds off the air pocket and delays regeneration during active water use, preserving the drain line and saving water with every cycle. Its deep bed and corrosion-resistant composite valve make it the workhorse choice for the most demanding iron and sulfur applications.

Shipped without media, this platform lets installers load the precise catalytic bed from the supplied chart. A 24" tank typically holds 5 cu. ft. of Birm or Centaur for sulfur (about 15 gpm), 10 cu. ft. of Birm for iron, or 10 cu. ft. of Katalox-Light® rated up to roughly 35 gpm service flow. Components include the NWS 1-1/2" Composite Control with Control Flow Technology, a remote meter, a gravel underbed, and the 24" x 72" mineral tank, giving you everything but the media to build a heavy-duty filter.

• Largest 24" x 72" mineral tank in the composite series
• NWS 1-1/2" Composite Control with Control Flow Technology
• Sulfur (Birm/Centaur): ~5 cu. ft. at about 15 gpm
• Katalox-Light®: ~10 cu. ft. up to roughly 35 gpm service flow
• Remote meter and gravel underbed included; media separate
• Shipping weight: approximately 413.67 lbs

The corrosion-resistant composite valve and 1-1/2" flow path handle big homes and heavy contaminant loads without ongoing chemical feed. Each cycle draws an air charge, backwashes the bed to flush oxidized solids, and returns automatically to service. Use the media chart to specify Birm, Centaur, or Katalox-Light® for your iron, manganese, or hydrogen sulfide problem, then add plumbing adapters to complete a powerful, long-lasting whole-house filtration system.

As the flagship of the composite-valve series, this 24" system is built for the toughest residential and light commercial water, where high flow and heavy contaminant loads would overwhelm smaller filters. Its deep bed keeps loading rates low for thorough oxidation and capture, while the media chart's 24" column guides precise sizing for sulfur, iron, or Katalox-Light®. With corrosion-resistant construction and demand-based regeneration, it is engineered to deliver dependable, chemical-free performance under demanding conditions year after year.
