Axeon N-4000 Reverse Osmosis System | 220V 4,000 GPD

The N-4000 doubles the N-2000's output to 4,000 GPD using a dual 4040 membrane array in a 1:1 vessel configuration. It also delivers significantly better system efficiency — 48% recovery versus 32% on the N-2000 — meaning more of your feed water becomes purified permeate and less goes to drain. Both models share the same AX-8000 controller platform, frame footprint, and 220V 8.5A electrical requirements.

Yes — like all thin-film composite RO membranes, the AXEON XE1-Series elements have a maximum free chlorine tolerance of 0 ppm. Chlorinated municipal tap water will degrade the membranes if fed directly into the system. A carbon block or catalytic carbon pre-filter stage must be installed upstream before the N-4000.

The AX-8000 is the N-4000's built-in automation hub. It monitors TDS and water temperature in real time on an LCD backlit display, manages pre-treatment lockout when feed conditions are out of spec, runs automated and manual flush cycles to maintain membrane health, and raises low/high pressure alarms. The tank level input function lets the system stop production automatically when a connected storage tank reaches capacity.

The N-4000 ships pre-plumbed, pre-wired, and fully assembled. On-site connections are limited to feed water (1" FNPT), permeate out (½" QC), concentrate drain (½" QC), and a 220V single-phase supply at 8.5A. A licensed electrician should verify your panel can support the dedicated 220V circuit — no plumbing fabrication or component assembly is required.

The 5-micron SDF-Series sediment pre-filter should be inspected monthly and replaced every 3–6 months depending on source water quality. The two XE1-Series membrane elements typically last 2–3 years under normal commercial use. Monitor permeate TDS via the AX-8000 — a rising TDS reading is the clearest indicator that membrane replacement is due. For high-mineral water, using Axeon S–200 Membrane Antiscalant can help extend the life of your elements.

Yes — the AXEON N-Series continues with the N-6000, N-8000, N-12000, and N-16000 — all running on 220V with the same AX-8000 controller. Models from the N-6000 upward step up to an 11.0A draw and a larger 32 × 24 × 55 in frame, so factor in both electrical capacity and floor space when planning an upgrade.
