Description of Series 300 and 320 Rainbow Chlorine/Bromine Feeders for residential and commercial pools.

The Rainbow Feeders have proven to be a reliable choice for both residential and commercial swimming pools and spas. They are an efficient, easy way to sanitize our pool. The Rainbow Models 300 and 320 automatic chlorine/bromine feeders not only save time, but also reduce manual handling of chemicals. Choose from Off-line (300 Series) for existing pools or In-Line (320 Series) for new or existing pool or spa installations. All are NSF listed for chlorine or bromine in pools or spas. Features:

Completely enclosed systems—no escaping fumes.
Troublefree designs—no special venting required.
50 PSI maximum operating pressure.
Top-loading makes it easy to add chemicals. Available in clear amber for easy tablet monitoring.

The freestanding Model 300 and the in-line Model 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.

These feeders 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.
