Pentair Inline Chemical Feeder

Pentair Rainbow 320 In-Line Automatic Chlorinator (Model R171096)

Professional-Grade, High-Capacity Chemical Feed System for Pools and Spas

The Pentair Rainbow 320 In-Line Automatic Chlorinator delivers powerful, reliable chemical dosing for both residential and commercial pools. Engineered for efficiency, this feeder seamlessly integrates with your pool's plumbing to automatically dispense slow-dissolving Trichlor or Bromine tablets, providing consistent sanitization for systems treating 6,500 to 27,000 gallons via bottom feed—and up to 70,000 gallons via top feed configurations.

Built to last, the 320 Series chlorinator features a durable, enclosed system that eliminates the need for special venting and prevents the escape of harmful gases. Its clear amber chamber allows for easy monitoring of tablet levels, while the top-loading design makes chemical refills fast and mess-free.
