by Pentair Aquatic Systems®

The efficient, easy way to sanitize your pool or spa

The Rainbow Model 300 Off-Line Automatic Chlorine Feeder by Pentair not only saves time but also reduces manual handling of pool chemicals. This automatic chlorine / bromine feeder 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 automatic chlorine feeder installs easily on the pressure side of your pool pump, downstream of the pool filter and heater. 

The freestanding Model 300 features an external fine-control valve that lets you adjust the feed rate to meet specific pool or spa requirements. This chlorine feeder is ideal for retrofitting existing pools for automatic sanitization. 

  • Completely enclosed system - no escaping fumes

  • Simple, trouble-free design - no special venting required

  • Top-loading makes it easy to add pool chemicals

  • Flow indicator allows a quick visual read of water flow

  • Check valve protects pool pump and heater against damage from back-up of highly chlorinated water

The Rainbow Model 300 automatic chlorine / bromine feeder will take the work and worry out of keeping your pool sparkling clean and ready to use!
