The Circupool SJ-40 is designed to deliver ultimate reliability and simplicity for your swimming pool. This complete salt water pool system is designed for pools with up to 40,000 gallons water capacity.
The Circupool SJ series delivers maximum reliability and value whilst being an affordable, economical salt system. These are a great product and an affordable solution to keep your swimming pool crystal clear without the use of chemicals.
This chlorinator is manufactured in the US and installation is simple and can be done DIY if you’re handy enough.

As default, the unit will ship with 220v switched on, however the instructions cover how to change it to 110v.
“Manufactured in the US”
The electrolytic cell is made out of “high-output” titanium and housed in clear material to allow perfect visibility of the chlorine production and inspection of the plates. The Circupool SJ-40 is constructed from heavy duty materials for durability and extended lifetime.
The unit is designed to automatically keep your pool crystal clear, producing salt pool water that is gentle to eyes, skin and hair all year round. Any need for chlorine is eliminated.
The SJ series can replace either a Pentair IntelliChlor system or a Hayward Aqua Rite system using an adapter kit with no cutting or plumbing needed.
This SJ series salt system has a lifespan of 10,500 hours.
Like most modern chlorinators, the SJ-40 features self cleaning functionality which is achieved by reverse polarity.
As mentioned, the Circupool SJ Series feature a clear cell housing which allows you to very easily and quickly inspect the condition of salt cell and the cell plates.
Daily operation of the unit is automatic and comes with a simple, user-friendly control unit. The control unit isn’t fitted out with loads of unnecessary buttons, dials and lights.
The control unit is an attractive blue-colored console featuring a range of LED indicators and a touch operated keypad. The LED indicators provide a an overview of the system status at a glance, including indicating if the pool needs more salt in it. The keypad allows functions such as operating the chlorine output and activating the boost mode (super chlorinate).
For ease of operation, it is recommended that the control unit be wall mounted or equally effective, mounted on a post. It’s all dependant on your installation situation. It is also recommended that the control unit be mounted in a space that is easily accessible. This will allow you to make use of the LED indicator display and easily determine the current operational status of the unit.
You’ll need to connect this unit with your pump unit so that it makes use of the pump timer. It doesn’t have it’s own timer so it needs to run off the pump’s timer which isn’t an issue as the chlorinator can only work when the pump is running anyway.
The product features a boost function for super-chlorinating which the manufacturer calls 125% True Boost Mode. (See our article on how to shock a salt water pool – click here).
The Circupool SJ40 chlorinator comes with a very respectable 5-year warranty and manufacturer Circupool will not penalize you for carrying out the installation yourself unlike other manufacturers who force you to use qualified installation technicians as a condition of their warranty.
Reviews on Amazon for this product are very positive – in fact finding a negative review is quite difficult. At time of writing, this product was the third best selling chlorinator on Amazon.
