AXEON RF-4000 4-Stage Reverse Osmosis System

The AXEON® RF-4000 is a 4-stage commercial and light industrial reverse osmosis system designed for applications requiring reliable, high-quality purified water. A multi-stage filtration process reduces sediment, chlorine, dissolved solids, and other contaminants that can impact water quality and downstream equipment performance.

The RF-4000 uses sediment and carbon pre-filtration, a high-rejection RO membrane stage, and post-filtration polishing to deliver consistent permeate quality. Well-suited for food service, beverage, laboratory, general process water, and light commercial grow applications. 100% tested and assembled in the U.S.A.
