Pool Chlorinator Model 300 Automatic Chlorine / Bromine | Upgraded Model

The R171016 Upgraded Pool Chlorinator is designed to be fully compatible with the Pentair Rainbow 300 automatic chlorine/bromine feeder. With significant design and material improvements, this unit offers enhanced durability, stability, and performance for pool owners seeking reliable water treatment.

Enhanced Control Valve Design:
Made from high-density materials, the upgraded valve prevents blockages from debris and resists chlorine corrosion. The improved internal diameter and structure solve common issues like leaks and cracking in the original Rainbow 300 valve, while offering smoother water flow adjustment.

Improved Water Treatment Capacity:
With an upgraded barrel design and redesigned valve, the Rainbow 300 chlorinator now treats up to 72,000 gallons, making it ideal for small, medium, and large in-ground pools or spa centers.

Stronger Base & Leak-Proof Lid:
A widened base increases contact with the ground for better stability, while the redesigned flat-threaded lid gasket improves the seal, preventing leaks during operation.

Easy Installation & Maintenance:
Includes all necessary parts for installation. To prolong the chlorinator’s lifespan, it is recommended to regularly lubricate the o-ring and control valve. Clean the valve and tubing with fresh water to avoid blockages.

Wide Compatibility:
This chlorinator is a direct fit for Pentair R171016 Rainbow 300 models and works seamlessly with most in-ground and above-ground pools and spa systems.

Take the hassle out of pool care with this upgraded and more durable version of the classic Rainbow 300 feeder.
