Product details
The Pentair Rainbow #300-29X is an offline commercial chlorinator, part number R171070. It is a heavy duty, high capacity tablet feeder for large residential and commercial pools.
Capacity and output
The feeder holds 29 large tablets or 237 small ones and dispenses 8.5 lbs. of 1 in. trichlor tablets in 24 hours. That output treats pools from 80,000 to 322,000 gallons. Across its sizes the Rainbow range covers pools up to 658,500 gallons.
How it works
An offline feeder is plumbed beside the return line rather than in it. A heavy duty 1/2 in. control valve and tubing meter the water that passes through the feeder, which optimizes flow and erosion of the tablets and lets the unit deliver larger amounts of sanitizer. Slow dissolving trichlor or bromine tablets both work.
Note on chemistry
Pick one tablet type and stay with it. Trichlor and bromine should never share a feeder.
