Zilmet ZAFL2234 ActiveFlo Lite Point of Use Water Conditioner

Optimize Water Quality with Zilmet ZAFL2234 ActivFlo Lite 3/4″ FNPT Point-of-Use Water Conditioner

Reduce limescale at fixtures and water-heating equipment—without salt, power, or backwash. The Zilmet ActivFlo Lite (MPN ZAFL2234) conditions hard water using a galvanic process so calcium forms less-adhesive crystals that are easier to flush away. Ideal at the water heater, tankless inlet, or other point-of-use locations, it helps maintain efficiency and flow while minimizing cleaning. A compact stainless housing with 3/4″ FNPT × 3/4″ FNPT threads installs in minutes and requires virtually no maintenance.

Save Water & Energy (No Salt, No Power)

With no brine, regeneration, or drain line, ActivFlo Lite helps heaters and fixtures stay cleaner so they run closer to design efficiency. That means fewer harsh cleaners and no electricity or salt purchases needed.

Everyday Performance You Can See

By promoting less-adhesive mineral crystals, the unit helps reduce scale on heat exchangers, aerators, and showerheads. It’s well-suited for water-heater and tankless inlets where scale can sap performance.

Durable Stainless Construction

A stainless steel body protects the internal galvanic element and resists corrosion in mechanical-room environments, supporting long service life with minimal upkeep.

Installer-Friendly, Bi-Directional

Standard 3/4″ FNPT female threads and bi-directional flow simplify retrofits. Mount horizontally or vertically per the submittal; just provide straight pipe and unions as needed for service access.

Sized Right For Point-Of-Use

With an optimum flow up to 4.2 GPM and max flow 12.4 GPM, this model is a natural fit for individual water heaters, small branch lines, and appliance feeds.

Built For Real-World Conditions

Rated up to 210 °F and 232 psi (see submittal), the unit handles typical domestic hot-water conditions. Always follow the installation manual and local code.

Low-Maintenance Operation

No media changes or backwash cycles—just periodic visual checks during routine service. If you need whole-home treatment, pair with appropriately sized ActivFlo models upstream.
