Pentair Rainbow® Model 300C Off-Line Automatic Chlorinator – Clear Amber Body

The Pentair Rainbow 300C Series Off-Line Chlorinator is engineered for efficient, high-capacity chemical feeding in residential and commercial pool systems. Designed to treat between 12,000 and 48,000 gallons, the 300C model accommodates up to 11 large or 98 small slow-dissolving Trichlor or Bromine tablets, delivering consistent, automated sanitization with minimal user intervention.

This model features a durable, see-through amber body that allows for quick visual confirmation of tablet levels, reducing guesswork and improving maintenance efficiency. The completely enclosed system eliminates escaping fumes, and the top-loading design ensures safe and simple chemical reloading without requiring special venting.

Ideal for retrofitting into existing setups, the 300C installs on the pressure side of the pool pump and connects easily with standard 1/4" feeder hoses, a precision control valve, and standard fittings. Operating at a maximum pressure of 50 PSI, this unit meets NSF certification standards, ensuring compliance for both residential and public installations.
