RUNXIN F77B1 Automatic Filter
The RUNXIN F77B1 Automatic Filter controls water filtration with ease. In addition, it handles up to 18 000 L/h, making it perfect for medium to large filtration systems. Moreover, the valve allows you to program backwash cycles using a clear LED display. As a result, it reduces manual work and ensures consistent filtration.
Furthermore, the F77B1 supports 2″ connections and offers flexible installation, either top-mounted or side-mounted. For example, its ceramic sealing faces prevent leaks and corrosion. Therefore, this automatic filter works well with sand filters, carbon filters, and pre-RO setups, making it ideal for industrial and commercial water treatment applications.
