Rainbow Model 300 - 29x

The Pentair Rainbow Model HC-3315 is a high-capacity, heavy-duty chemical feeder designed for high-volume sanitization in commercial or large residential swimming pools and spas. This robust unit is engineered for offline installation using 1-inch hard plumbing and operates via a pressure differential system to consistently dispense either trichlor or bromine slow-dissolve tablets. The feeder itself has a shipping weight of approximately 9 pounds when empty and features a substantial internal capacity capable of holding up to 15 pounds of chemical tablets. Built to withstand demanding environments, the HC-3315 includes a heavy-duty control valve for precise feed rate adjustments and a completely enclosed system that prevents the escape of hazardous gases, ensuring efficient water treatment for pools up to 97,600 gallons with chlorine or 20,200 gallons with bromine.
