Aquamor® UltraFiltration Systems

Ultrafiltration Systems

A self-cleaning 0.015-micron hollow-fiber membrane that fits on standard line pressure and scales from a single foodservice equipment run to a whole-home point-of-entry installation, without changing the product.

How Ultrafiltration Works

A 0.015-micron mechanical barrier, not a chemical process

Ultrafiltration works by forcing water through hollow-fiber membranes with a nominal pore size of 0.015 micron. At that scale, the membrane physically blocks cysts, turbidity, and suspended particles, no chemistry, no consumable media.

  • 0.015-micron nominal pore size, hollow-fiber membrane construction; particle reduction is mechanical, not adsorptive.
  • NSF/ANSI 53 certified for cyst reduction, Cryptosporidium and Giardia. Certification designations: AQ UF-20 (20-inch configurations) and AQ UF-40 (40-inch configurations).
  • Self-cleaning automatic backwash, the programmable controller triggers a quick-pulse backwash cycle on a set schedule, which keeps differential pressure low and extends membrane service life without a manual intervention.
  • Standard line pressure, no booster required, operates at 30 to 85 psi on city or well water without an additional pump in most applications.
  • Up to 5-year membrane service interval, source-water dependent; replacement membranes are a standard stocked SKU.

Built on filtration technology patented by Aquamor's founder (U.S. Patents 11,072,540; 10,590,006; 10,087,085).

Four Systems: One Platform

Single or double membrane, 20-inch or 40-inch

The UF-42xx family scales flow rate by adding membrane length and count. All four models share the same 0.015-micron hollow-fiber construction, the same 30 to 85 psi operating envelope, and the same Build-on-the-Wall footprint. Size to the application, not the platform.

All UF-42xx models: 120 V AC / 60 Hz controller; Build-on-the-Wall modular platform; NSF-certified components; optional NSF post-filtration packages for chlorine and chloramine reduction. Per-model width and height dimensions are listed on each system card above.

Two Markets, One Product Line

The same hardware, positioned for each installation context

The UF-42xx line is dual-channel by design. Foodservice operators and water treatment professionals buy the same physical product, the difference is how it is sized, positioned, and supported for each application.

For Foodservice Operations

Ice machines, brewers, and beverage equipment protection

In a foodservice environment, the UF system sits at point of entry to protect ice machines, coffee brewers, cold-beverage dispensers, and steam equipment. The automatic backwash controller runs silently between service visits; NSF/ANSI 53 cyst reduction is documented, not asserted.

  • Point-of-entry protection for ice machines, coffee, cold-bev, and steam
  • 8 to 30 GPM, sizes to a single equipment run or a full QSR line
  • NSF/ANSI 53 certified for cyst reduction (AQ UF-20, AQ UF-40)
  • Self-cleaning controller reduces service call frequency
  • Optional NSF post-filtration for chlorine and chloramine reduction

For Water Treatment Professionals

Whole-home and small-commercial point-of-entry

For plumbing contractors and water treatment dealers, the UF-42xx is a wall-mounted POE particulate barrier for whole-home and small-commercial jobs on city or well water. Published dimensions, standard MNPT connections, and the self-cleaning controller make this a system you can size, document, and stand behind.

  • Whole-home or small-commercial POE, city or well water
  • No booster pump required in most applications (30 to 85 psi range)
  • 1-inch and 3/4-inch MNPT connections, clean integration
  • Published dimensions for permit documentation
  • NSF/ANSI 53 certified for cyst reduction, spec-sheet-ready

For high-volume foodservice applications requiring integrated UF and RO: The RED Integrated UF + RO System (Part No. 108048) is a compact, wall-mounted modular system combining the 40-inch UF membrane with reverse osmosis, configurable to fit most available wall space. It is available separately and handled through the Aquamor foodservice team. Contact us for details.
