This 1000gal Sand Filter helps keep a constant flow of clear and clean water in your swimming pool.This filter will remove debris such as leaves, bugs and helps prevents your pool looking unsightly and smelling. A cost effective and environmentally way to upgrade your pump.This filter uses 18kg of Silica Sand to filter out the dirty water and can last up to three years, unlike a standard pump which needs to be changed every two weeks in the warmer months.The filter is connected to your pool via an outlet and inlet valves. The outlet valve pumps the dirty water through the filter collecting the dirt and debris and then pumps the clean water back into the pool via the inlet pump, before repeating this process, keeping your pool clean and fresh.Once the sand filter is full you don’t need to worry about replacing the filter, simply turn the filter to backwash, once this has been completed make sure the waste hose is attached and then set the pump to rinse and the debris is dumped in an appropriate area of your back garden.This Sand Filter is compatible with 15ft-18ft Steel Frame and Fast Set pools.Designed to make cleaning your pool simple and easy.FeaturesPump Flow Rate: 3,785L/hrSystem Flow Rate: 3,785L/hrRating: 220-240V 50HzRequires: 18kg of sand.
