3/4-Inch Inline Point-of-Use Water Conditioner

The Zilmet ActivFlo Lite 3/4" (MPN: ZAFL2234) is a salt-free point-of-use water conditioner designed to protect tankless water heaters, traditional tanks, and downstream fixtures from hard water limescale accumulation.

Key Features

Designed for Water Heater & Equipment Protection

Engineered for installation on cold water inlets to protect tankless water heaters, storage tanks, and targeted branch lines from scale buildup without restricting flow.

Galvanic Alloy Conditioning Technology

Uses an internal galvanic alloy element to alter dissolved calcium minerals into less-adhesive crystals, preventing scale from plating out on heat exchangers, aerators, and heating elements.

Bi-Directional Inline Flow Design

Features bi-directional 3/4-inch FNPT x 3/4-inch FNPT threaded connections that allow water to flow in either direction, simplifying pipe orientation during installation.

Zero-Power & Salt-Free Operation

Operates passively on water pressure without electricity, salt brine, chemical additives, or backwash drain lines, eliminating water waste and ongoing operational costs.

Zilmet ZAFL2234 FAQ

Where is the Zilmet ActivFlo Lite ZAFL2234 best installed?

It is specifically sized for point-of-use application directly on the cold water inlet feeding a tankless or tank water heater, branch lines, or specific equipment requiring scale protection.

Does the ActivFlo Lite affect water direction during plumbing hookup?

No. The unit features a bi-directional internal design, allowing water to flow through in either direction without restricting performance or conditioning efficiency.

Does this unit require electrical wiring or a drain connection?

No. The unit operates passively via fluid movement without electricity, control boards, salt, or backwash drain line tie-ins.

Can the ZAFL2234 handle high-temperature domestic hot water loops?

Yes. The heavy-duty stainless steel casing and galvanic element are rated to handle temperatures up to 210°F and pressures up to 232 PSI.

What is the difference between optimum working flow and maximum flow rate?

The optimum working flow rate of up to 4.2 GPM is the ideal operating range for maximum galvanic scale reduction performance, while the unit can handle peak flow demand up to 12.4 GPM without excessive pressure drop.
