The Rainbow Model 320 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. The Rainbow Model 320 installs easily on the pressure side of the pump, downstream of the filter and heater.

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

Standard with 2 inch slip PVC fittings and adapters for 1-1/2 inch.
