Runxin F77BS Manual Filter – Powerful & Controlled Filtration

n

The Runxin F77BS manual filter provides a reliable, hands-on solution for sand, carbon, or multimedia filter systems. Because you operate the backwash manually via the handwheel, you precisely control when to clean the media. Moreover, this control helps you avoid unnecessary backwash cycles, and as a result, you conserve water. In addition, the valve’s high-capacity design supports heavy-duty filtration while maintaining efficient performance.
