This filter pump is designed to keep the water in the pool clean. It comes with 100 filter balls. The filter pump has a flow rate of 4.4 m³/h. It has a durable, corrosion-resistant tank. The included cotton filter balls effectively filter out even the smallest particles. They are lightweight and easier to handle than other filter materials such as sand. The filter effect of 550 g of filter balls is equivalent to that of 20 kg of filter sand. In addition, the filter balls require a lower working pressure, so that less energy is consumed. The filter pump is equipped with an easy-to-read pressure gauge. Please note that no connection hose is included.
