D14WL2NAF: Low-Flow NSF Certified Chlorinator

The D14WL2NAF is a reliable, NSF-certified chlorinator designed for water treatment applications that require accurate and consistent chemical injection. Using Dosatron's water-powered dosing technology, it delivers proportional injection ratios from 1:500 to 1:50 (0.2% to 2%), automatically maintaining the selected concentration as water flow changes. Certified to NSF/ANSI 61 & 372 standards, the unit is suitable for water potabilization, disinfection, and sanitation applications where both performance and compliance are critical. By eliminating the need for electricity and continuously adjusting dosing to match flow demand, the D14WL2NAF helps improve treatment consistency, reduce chemical waste, and simplify day-to-day operation.

For optimal dosing accuracy and long-term reliability, the D14WL2NAF should be installed on a properly configured treatment line or NSF-recommended bypass system. Upstream filtration is recommended to prevent debris from entering the injector and affecting performance, while isolation valves can make routine maintenance faster and more convenient. Because the unit is commonly used in potable water and sanitation applications, appropriate backflow prevention measures should be incorporated to protect the water supply. Keeping the chemical source close to the injector and minimizing suction lift helps maintain stable chemical pickup and accurate dosing. A well-designed installation supports dependable operation, regulatory compliance, and consistent water treatment results.
