Hayward 9 lb Off-Line Automatic Chemical Feeder (CL220EF)

Take the hassle out of daily pool maintenance with the Hayward CL220EF Off-Line Automatic Chemical Feeder. Engineered for performance and durability, this heavy-duty chlorinator works seamlessly with your pool's existing pump and filtration system to automatically deliver a steady, controlled stream of sanitizer.

With a high-capacity 9 lb chamber, the CL220EF holds up to two weeks' worth of slow-dissolving Trichlor or Bromine tablets or sticks. This means fewer trips to the equipment pad and more time enjoying crystal-clear water.

Why Choose an Off-Line Feeder?

Because this is an off-line model, it installs outside your main plumbing line using the included flexible tubing and saddle clamps. It is the perfect solution for aftermarket retrofits, tight equipment pads, or filtration setups where cutting into existing rigid PVC pipes isn't practical.

Key Features

• 9 lb High-Capacity Chamber: Holds up to 18 large 3-inch tablets or mini-tabs, providing up to two weeks of continuous, automatic sanitization for large residential or commercial pools.
• Precision Dial Control Valve: Features a built-in control valve that lets you easily adjust the water flow and fine-tune your chemical feed rate between "FULL" and "OFF" to match your pool's exact chlorine demand.
• Easy-Lok™ Threaded Cover: Designed for safe, quick, and convenient access when refilling. The ergonomic lid unscrews easily, while the unique integrated finger-release catch provides an extra layer of security.
• Heavy-Duty, Corrosion-Proof Construction: Built from premium, durable ABS thermoplastic with a high-quality Viton/X-Ring seal to withstand harsh pool chemicals and extreme weather exposure without breaking down.
• Integrated Check Valve: Features a built-in non-return check valve to reduce the backflow of concentrated chlorine gas, protecting your expensive pool equipment (like heaters and filters) from premature corrosion.
