Zilmet ActivFlo Lite, Hot Water Conditioner

Zilmet ZAFL2234 ActivFlo Lite Water Conditioner – 3/4" FNPT, 232 PSIG, 210°F Max

The Zilmet ZAFL2234 ActivFlo Lite Water Conditioner is a professional-grade inline treatment device engineered to mitigate the effects of hard water in residential and light commercial plumbing systems. Designed for direct installation in 3/4" FNPT water lines, it prevents scale buildup, preserves system efficiency, and maintains flow integrity without the use of salt, power, or chemicals. The ActivFlo Lite operates passively, using a catalytic process to alter calcium crystal formation, reducing mineral adhesion to plumbing surfaces and water-heating equipment. Built for durability and reliability, it provides consistent performance under high-temperature and high-pressure operating conditions.

Performance and Application

The Zilmet ZAFL2234 ActivFlo Lite Water Conditioner is engineered to improve hydraulic efficiency in plumbing systems affected by hard water. Its internal catalytic chamber modifies the crystalline structure of calcium and magnesium, reducing their ability to adhere to surfaces such as pipes, valves, and heat exchangers. This helps maintain consistent flow and extends the service life of downstream equipment including water heaters, dishwashers, and fixtures. The unit operates without external power, moving parts, or maintenance, making it suitable for continuous use in hot and cold water lines. With a rated maximum operating pressure of 232 PSIG and temperature limit of 210°F, the conditioner supports both domestic and light commercial system requirements.

Summary

The Zilmet ZAFL2234 ActivFlo Lite 3/4" FNPT Water Conditioner provides a durable, maintenance-free solution for managing hard water in professional plumbing applications. With high temperature and pressure tolerance, corrosion-resistant construction, and catalytic conditioning technology, it delivers consistent, long-term performance across residential and light commercial water systems.
