The Water Technology CF50 Cartridge Pool Filter provides efficient, easy-maintenance filtration for residential swimming pools, spas and suitable semi-commercial pool applications.

With a generous 4.63m² filtration area and maximum flow rate of 190 litres per minute, the CF50 offers increased filtration capacity while retaining the compact, lightweight design of the CF Series.

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 provides convenient monitoring of operating pressure.

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