1-Inch High-Flow Whole-House Catalytic Water Conditioner

The Zilmet ZAF010H High Flo ActivFlo 1" (MPN: ZAF010H) is a heavy-duty, salt-free catalytic water conditioner engineered for 1-inch main supply lines, providing whole-house scale protection across high-demand residential plumbing systems without electricity or chemical maintenance.

Key Features

Engineered for High-Flow Whole-House Protection

Sized specifically for 1-inch main cold water lines, supplying whole-home scale conditioning to protect water heaters, boilers, plumbing fixtures, and appliances throughout the entire property.

High-Volume Catalytic Flow Range (5.9 – 15.9 GPM)

Designed to handle high peak demands with an optimal continuous flow capacity of 5.9 GPM to 15.9 GPM, maintaining effective catalytic conditioning across simultaneous fixture usage with a minimal pressure drop of just 0.5 PSI.

Patented Catalytic Alloy Conditioning Technology

Utilizes an internal catalytic alloy core to alter dissolved calcium bicarbonate into stable, non-adherent aragonite micro-crystals that pass harmlessly through the system without forming scale on heat exchangers or fixture nozzles.

Zero-Power & Maintenance-Free Passive Operation

Operates passively on line water pressure without requiring electrical hookups, salt replenishment, chemical additives, or backwash drain lines—eliminating wastewater generation and ongoing upkeep costs.

Heavy-Duty Lead-Free Stainless Steel Construction

Built with a 1-inch MNPT threaded stainless steel housing rated for working pressures up to 232 PSI and operating temperatures from 35°F to 180°F, backed by a 15-year manufacturer warranty.

Zilmet ZAF010H FAQ

How does the Zilmet High Flo ZAF010H prevent limescale without salt?

As water flows over the internal catalytic alloy core, fluid turbulence and catalytic contact transform dissolved calcium and bicarbonate ions into insoluble aragonite crystals. These inert crystals remain suspended in the water stream rather than bonding to pipe walls, heat exchangers, or appliance internals.

What makes the ZAF010H different from standard 3/4-inch ActivFlo models?

The ZAF010H features larger 1-inch MNPT threads and a significantly higher flow profile (5.9 to 15.9 GPM vs. 1.9 to 5.9 GPM on the 3/4" model). It is built specifically for larger homes or higher-volume main supply lines where maintaining high flow capacity with negligible pressure drop (0.5 PSI) is critical.

Does this unit require electrical wiring or a drain connection?

No. The ActivFlo ZAF010H operates completely passively via inline fluid movement without power connections, control boards, salt tanks, or backwash drain lines.

Where should the ZAF010H be installed?

It should be installed inline on the main cold water service line after the primary shutoff valve or backflow preventer to provide point-of-entry (POE) conditioning for the entire home.

Does the internal catalytic media require replacement over time?

No. The internal alloy core is non-sacrificial and does not wear down or require periodic media recharges, providing zero-maintenance scale reduction backed by a 15-year warranty.
