The Hayward CL220EF Off-Line Automatic Chlorinator provides reliable, consistent chlorination for new or existing pools and spas. Built from durable, corrosion-proof materials, this feeder works automatically with your pump and filter system to deliver steady chlorine levels with minimal effort.

Designed for simple off-line installation, the CL220EF is ideal for retrofit applications, tight equipment pads, or systems where in-line installation isn’t practical. The unit accepts both large and small slow-dissolve chlorine tablets or sticks, giving you flexibility in how you sanitize your pool.

An Easy-Lok™ threaded cover provides safe access for adding tablets, while a dial control valve lets you fine-tune the chlorine feed rate for precise sanitization control.
