Erosion Feeders

Rainbow Erosion Feeders

Rainbow Automatic Chlorine/Bromine Feeder

These lower capacity feeders are designed for smaller commercial pools and spas and use large or small trichlor or bromine slow-dissolving tablets. The feeder installs on the pressure side of the pump, downstream of the filter and heater.

When installed above water level, all models except for #52-604 automatically drain so chemical tablets do not continue to soak when the pump is shut off. These feeders are top loading with no need to replace expensive cartridges and feed directly into the pool down line of all equipment. No special wiring is required. All parts are replaceable (not recommended for use with copper plumbing). All models are NSF listed except for #52-607.
