A filtering element of the cold water with quartz sand that purifies water from mechanical impurities, rust and precipitation with double effectiveness. The water is purified in a similar manner to spring water flowing through layers of grit. In this element, water flows through a polyester tubing and fine sand. Such structure of the filtering element ensures the highest effectiveness of the mechanical purification and eliminates water turbidity caused by mechanical impurities. Flow rate: ~ 40 litres per minute. Resistance to water flow: ~ 20%. The source of purifyable water: up to 8000 litres. Maximum water temperature: 38°C.
