Hozelock Saturn Pond Pre Filter

Revolutionary NEW Pre filter. Stops solids reaching your filter.At last a product that puts an end to messy filter cleaning! The Saturn pre filter sits just before your pumped water hits your filter. The dirty water from your pump is spun around a circular polyester gauze filter. Particles are trapped by the gauze and then removed by a rotating jet, which is located inside the filter to constantly clean the gauze from the inside. Dislodged particles fall into a large debris collection area at the bottom of the unit. Clean water then passes through to your biological filter.
