Automatic Chlorine Dispensing Systems from Star-Pool

Pentair Rainbow 320 and 300 Automatic Chlorinators

Rainbow™ Models 300 and 320 automatic chlorine/bromine feeders not only save time, but also reduce manual handling of chemicals. They use large or small Trichlor or Bromine slow-dissolving tablets to make sanitizing your new or existing pool or spa easy and automatic. Both install easily on the pressure side of the pump, downstream of the filter and heater.

The freestanding Rainbow 300 and the in-line Rainbow 320 both feature an external fine control valve that lets you adjust the feed rate to meet specific pool or spa requirements. The 300 is ideal for retrofitting existing pools for automatic sanitization. The 320 is designed for permanent installation in the return line of new or existing systems, and dispenses sanitizer directly into your pool or spa, downstream of all equipment.

• Completely enclosed systems—no escaping fumes.
• Simple, trouble-free designs—no special venting required.
• Top-loading makes it easy to add chemicals.
