Backwash Disk Pre-filters

RUNXIN provides two backwash disk pre-filter types: manual and automatic, and our backwash pre-filters feature an exceptional performance that is second to none. The valve core is installed upside down, thus improving backwash cleaning efficiency by 30%. This step also provides the first layer of protection of residential water supplies by removing sediment, rust, and other particles. The backwash disk pre-filter is also equipped with a leakage sensor to emit a signal, that, once received, ensures the pre-filter closes the inlet valve.
