Advanced Filtration Technology: Featuring 40 filter, 40 precision can effectively large particles such as sand, rust, and red worms, extending the lifespan of subsequent water purification devices and maintaining optimal performance. Water pressure gauge for real-time water pressure monitoring: The intuitive water pressure data table can observe water pressure changes in real time, and users can adjust the water pressure according to the size of the water pressure. Cost-Effective and Maintenance-Friendly: The filter's ability to be flushed and reused after collecting sediment translates into significant savings on replacement costs and helps reduce the frequency and expense of appliance repairs caused by water impurities. Energy Efficient Design: Operating without the need for electrical power, this sediment filter utilizes natural water pressure, promoting energy conservation and environmental sustainability by reducing unnecessary energy consumption. 6-ton large flow: the water filtration volume can reach 90/min, and the high floor does not affect the water pressure. The water consumption of large-sized villas can also be easily satisfied without affecting the water pressure, and the high floor and large-sized villas can maintain a large water volume 1.
