Ultrafiltration Systems

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.

Exploded view of the Aquamor UF system assembly

The UF-42xx membrane technology is 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.

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 plumbing 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 Plumbing

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

For plumbing professionals, 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 multi-stage skid combining the 40-inch UF membrane with reverse osmosis on a single base. It is available separately and handled through the Aquamor foodservice team. Contact us for details.
