★ The third generation patented gold cylinder long-term pressure control technology, subversive design, automatic voltage regulator within 4 kg of safety value, to ensure the safety of the back-end water;
★Two-way action cylinder pressure control principle, the pressure control range is larger and more precise;
★The pressure-control parts are made of brass forging, which is more than 10 times more durable than the traditional diaphragm type.
★The fourth generation full-effect sewage treatment patent technology, which combines siphon backwashing + double-sided scraping technology + surround speed suction + large particle discharge;
★The real no-cleaning technology, the scraping technology can thoroughly clean the dirt on the screen and the surface of the filter bottle. The siphon backwash can thoroughly clean the inlaid impurities inside the mesh hole.
★The filter bottle adopts BSK formula + original imported material, does not contain bisphenol A, and is tested by NSF and SGS. After the modified formula of Besikang, it can withstand the freezing test of -30 °C; the bursting pressure is more than 60 kg, water hammer 12 kilograms and more than 150,000 times; exceeding the NSF pipeline standard;
