The efficient, easy way to sanitize your pool or spa.

The Rainbow Models 320 automatic chlorine/bromine feeder not only saves time, but also reduces manual handling of chemicals. It uses large or small Trichlor or Bromine slow-dissolving tablets to make sanitizing your new or existing pool or spa easy and automatic. It installs easily on the pressure side of the pump, downstream of the filter and heater.

The in-line Model 320 features an external fine control valve that lets you adjust the feed rate to meet specific pool or spa requirements. 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.

Features
Completely enclosed systems - no escaping fumes.
Simple, trouble-free designs - no special venting required.
Top-loading makes it easy to add chemicals. Also available in clear amber for easy tablet viewing.

Save time, reduce manual handling of chemicals.

Whether you choose the free-standing Model 300 or the in-line Model 320, Rainbow automatic chlorine/bromine feeders will take the work and worry out of keeping your pool sparkling clean and ready to use.
