Keep your pool water clear, clean and ready to swim with the Zodiac Ei Classic Saltwater Chlorinator.

It is suitable for new or existing in-ground pools and works with all pool surface types.

The Zodiac Ei Classic is built for practical, low-maintenance pool care. Its automatic reverse polarity helps reduce calcium build-up on the cell, which means less manual cleaning and more reliable performance over time. The clear cell housing also makes inspection easy, while the LED interface provides simple status feedback for no flow, low salt and output settings.

Built with long-lasting titanium electrodes and designed for domestic swimming pool use, the Zodiac Ei Classic combines durability, ease of use and dependable chlorination in one compact unit. Available in Mini and Midi models, it suits a range of pool sizes and is a strong option for pool owners upgrading from manual chlorination or replacing an older salt chlorinator.

FAQ's

What does the Zodiac Ei Classic Saltwater Chlorinator do?
It automatically converts pool salt into chlorine gas for easier pool maintenance, while helping create softer-feeling water that is gentler on sensitive skin.

How much salt does a chlorinator use?
Initially, add about 25kg of pool salt for every 5 000 litres of pool water to establish the correct salt level. After that, you generally only need to replace the salt lost through sandfilter-backwashing and splash-out. In most cases, this is not more than 20kg every 6 months for a 40 000-litre pool. 

Is the Zodiac Ei Classic self-cleaning?
Yes. It uses automatic reverse polarity to help reduce calcium build-up on the cell, which lowers maintenance requirements. 

What pool size is the Zodiac Ei Classic Mini suitable for?
The Mini model is recommended for pools up to 60 000 litres. 

What pool size is the Zodiac Ei Classic Midi suitable for?
Zodiac South Africa lists the Midi for pools up to 100 000 litres.

Does the Ei Classic have a Boost function?
Yes. The Boost function increases chlorine production when extra sanitising is needed. 

Can the Zodiac Ei Classic be used on fibreglass, marbelite or vinyl pools?
Yes. It is designed for in-ground pools and compatible with all pool surface types.
