Product Information


The Rainbow Model 302 Off-Line Automatic Chlorine or Bromine Spa Feeder will treat spas from 500 to 2,000 gallons per day and includes a spa chamber. This model 302 is freestanding and holds 15 small chlorine tablets. The feeder uses small Trichlor or Bromine slow-dissolving tablets to make sanitizing your existing spa easy and automatic. Plus, the Rainbow Model 302 installs easily on the pressure side of the pump, downstream of the filter and heater.

The Rainbow 300 Series will retrofit into existing spas. They not only save time, but they also reduce manual handling of chemicals. The Pentair automatic feeders feature an external fine control valve that lets you adjust the feed rate to meet specific pool or spa requirements. The check valve protects the pump and heater from back-up of highly chlorinated water.

The Rainbow Automatic Feeders are completely enclosed systems, so no escaping fumes. with the simple, trouble-free design, no venting is necessary. They are top loading which makes it very easy to add chemicals. And extensions are available to increase tablet or stick capacity, in case you are away for an extended period.

The Series 300 off-line feeders are for retrofit installations. For more capacity in your spa feeder, see models 300-19 and 300-29.
