The Water Technology CF100 Cartridge Pool Filter provides high-capacity, easy-maintenance filtration for residential swimming pools, spas and suitable semi-commercial pool applications.

With a generous 9.4m² filtration area and maximum flow rate of 392 litres per minute, the CF100 is the largest model in the CF Series, offering increased filtration capacity for higher-flow pool systems.

The UV-resistant filter tank features a heavy-duty ring-lock lid for convenient access to the cartridge element, making routine cleaning and replacement straightforward.

Unlike traditional sand filters, cartridge filters do not require routine backwashing, helping reduce water wastage during maintenance.

A screw-type air bleeder allows trapped air to be released from the filter tank, while the oil-filled pressure gauge makes it easy to monitor operating pressure.

Supplied complete with cartridge filter element, pressure gauge and union connections.

What size pump can I use with the CF100?

The CF100 has a maximum rated flow of 392 litres per minute (23.52m³/h). Your pump's actual operating flow must remain within the filter's rated capacity.

Can I use this filter for a spa pool?

Yes, provided the water temperature does not exceed 40°C and the system is compatible with the filter's pressure and flow ratings.

How do I know when the cartridge needs cleaning?

Monitor the pressure gauge and follow the manufacturer's cleaning instructions. An increase in pressure compared with the clean-cartridge reading can indicate that cleaning is required.
