Highlights
Engineered to withstand pool chemicals, ensuring the tank remains structurally sound and corrosion-free for years to come
Features a clear viewing lid that allows for instant visual checks of the filtration process and media condition without having to open the system
Equipped with a built-in pressure gauge and a 6-way side-mounted valve, giving you precise control and an easy way to see exactly when the system needs backwashing
Built to handle demanding environments with a 2.5 bar pressure rating and resistance to water temperatures up to 43°C, making it ideal for heated pools and harsh climates
Designed with a large-diameter sand and water drain to make winterising your pool or performing media changes significantly faster and less labour intensive
The internal top diffuser ensures water is spread evenly across the entire sand bed, preventing “channelling” and maximizing filtration efficiency
Supplied with stepped union adaptors 50mm/1½ inch (63mm/2 inch for S700B) for a secure, leak-free connection to both Imperial and Metric systems, simplifying the installation process
Enjoy peace of mind with a 3 year warranty on the tank and a 1 year warranty on the multi-port valve

If you are replacing a filter that forms part of an existing system then your replacement should match the size of the existing filter.
For example if you already have a 20 inch filter and 1.0HP pump on a 20m³ pool then you would still need 20 inch filter, alternatively you would need to replace both the pump and filter with a smaller selection as per our sizing guide below.
